  • the present disclosure relates to alarm or alert systems.
  • the present disclosure relates to alarm or alert systems that are provided in the occupant compartment of passenger vehicles.
  • the term“vehicle occupants” encompasses a driver and any passengers.
  • the occupant compartment means the volume of a vehicle housing accommodation for the vehicle’s occupants, comprising 2, 3, 4, 5 or more seats, and includes any separate driver compartment and the driver location. Access to the occupant compartment is effected by the opening of doors typically located at the side of the vehicle. Such vehicles usually have 2 or 4 doors providing access to the l occupant compartment, although the skilled person will readily appreciate that the number of doors is not limiting.
  • the doors to which the invention relates are typically considered to be doors that are attached by way of conventional, vertical hinges, although the skilled person will readily appreciate that the invention is equally applicable to any kind of door, including sliding doors, folding doors or so-called“gull wing” doors.
  • Systems for detecting road users in the vicinity of a vehicle from which an occupant may be about to alight are known from, for example, GB2505763, assigned to Daimler AG, whereby cameras detect the presence of road users including cyclists and pedestrians.
  • the system further detects the approach of a vehicle occupant’s hand towards the interior door handle of the vehicle and triggers an alarm when a potential collision between an opening door and a passing road user is likely.
  • a system disclosed in FR2797422 uses switches or capacitive sensors to detect the approach or touch of the hand of a vehicle occupant on the interior door handle before triggering an alarm alerting third party road users to the imminent opening of a vehicle door.
  • the alert may be ineffective due to distractions caused by the road environment and the noise of other road users.
  • the present invention provides an alert system for the occupant compartment of a vehicle, the alert system comprising: at least one sensor configured to respond to pressure exerted upon the sensor by a vehicle occupant in the process of exiting the occupant compartment of the vehicle by transmitting a trigger signal to at least one alarm device, the at least one alarm device responsive to the trigger signal to create an alarm the intensity of which is greater on the inside of the vehicle than it is on the outside and the system comprising sensors solely internal to the occupant compartment.
  • an alarm or alert system that in one or more embodiments can be retrofitted to existing vehicles without significant modifications being required, bringing the protection provided by more sophisticated alarm or alert systems to a wider proportion of road users.
  • providing an alarm or alert system that detects when a door is likely to be opened before emitting an audible and/ or visual alert may remind vehicle occupants to check before opening a door.
  • the at least one sensor may be situated in any suitable location in the interior of the vehicle; particularly of the occupant compartment that an occupant of a vehicle is likely to touch, press or engage with as they prepare to alight from the vehicle. Suitable locations include interior door handles, seatbelt releases, a central locking release button, an ignition key lock mechanism or similar. Notably, all of the sensors are located inside the vehicle, more particularly inside the occupant compartment of the vehicle.
  • the at least one sensor is affixed to a door handle, should a vehicle occupant accidentally or inadvertently get close to actuating the door handle or irresponsibly attempt to actuate the door handle at an inappropriate time during vehicle motion, the vehicle occupants will be alerted. This may be for example, if children are present in the vehicle, and is not dependent on whether or not the child locks (if fitted) are engaged.
  • the at least one sensor may be attached to or included within the suitable locations in the occupant compartment in any way considered suitable by the skilled person. However, to minimise the need to modify or damage the interior fittings of the vehicle to which the alarm system is to be fitted, the at least one sensor and the at least one alarm device may be fitted by an adhesive.
  • At least the at least one sensor is attached to a suitable location by way of an adhesive, for example, a pressure-sensitive adhesive.
  • an adhesive for example, a pressure-sensitive adhesive.
  • biomimetic systems such as so-called gecko tape may be used.
  • the at least one sensor may be mounted on a sleeve that fits to retain it around an interior fitting, such as around an interior door handle. The sleeve may be retained in place by tension, with an adhesive or other suitable retention arrangement.
  • the at least one sensor may be included within or upon the surface of the suitable locations at manufacture.
  • the at least one sensor may take a number of different forms as long as it is capable of registering pressure applied thereto above a given threshold.
  • the given threshold may be set to be a brushing contact, but is optionally set to register a greater pressure such that the at least one sensor is triggered when it is actually being pressed, i.e. a pressure action which may be indicative of a deliberate pressure on the sensor.
  • sensors suitable for one or more embodiments of the present invention are membrane switches including capacitive switches, dome switches, piezo switches, tactile switches and resistance switches, although the skilled person will realise that other types of sensors may be suitable.
  • tactile switches, dome switches and broken electrical contact switches, all of which require physical movement of an actuator will be referred to hereafter as displacement switches.
  • the at least one sensor may provide haptic feedback either to assist an occupant of a vehicle to which an embodiment of the system has been fitted to locate the sensor with their fingers, or to provide an indication that the sensor has been actuated.
  • haptic feedback include tactile features such as pips or ridges that serve to differentiate the switch from the surrounding area to which is has been applied.
  • haptic feedback may be active such as taking the form of vibrations, or apparent temperature differences resulting from, for example, a difference in thermal conductivity between the materials of the sensor and those of the surrounding area to which it has been applied.
  • the at least one sensor components may be integrally formed within a door handle or other suitable location, such that haptic feedback may be provided by a part of or the whole of a suitable location.
  • a suitable location such as a door handle may comprise the at least one sensor and a haptic feedback mechanism as described in the foregoing.
  • a door handle may vibrate in response to activation of the at least one sensor. This would provide an immediate alert to the user via the very mechanism by which a potential accident may occur, thereby having a synergistic effect which may overcome the present issue that the claimed subject-matter seeks to resolve.
  • false alerts may be avoided, such as those being triggered when part of an occupant’s body, an item of clothing or a piece of luggage are inadvertently brought into the vicinity of the at least one sensor, as the at least one sensor requires positive pressure to be applied in order to be activated.
  • the different pressures required to actuate the different parts of the sensor provides additional protection against false alarms.
  • different types of switches can be combined within a single instance of a sensor such that that sensor responds to different stimuli according to where it is touched. For example, a switch with a low actuating pressure may be located adjacent to another switch that has a higher actuating pressure such that an embodiment of the system is responsive to changing conditions applied to at least one sensor.
  • Such a structure may inhibit or reduce the occurrence of false positives or activate the higher pressure switch so that it is only active when the low pressure switch has been activated, which may reduce power consumption.
  • the displacement switch may be activated by the displacement of a vehicle door so as to further provide a mechanism to avoid false positives.
