The vehicle occupant detection system includes: a controller; a plurality of life detection sensors, wherein the plurality of life detection sensors are installed within an interior cabin of a mass-transit vehicle and are each associated with a life detection zone; a local warning system having at least one human-machine interface (HMI) output device; and a vehicle interface that communicatively couples the controller to a vehicle electrical system of the mass-transit vehicle. The vehicle occupant detection system is configured to: (i) acquire sensor data by scanning the life detection zone using the plurality of life detection sensors; (ii) determine whether an occupant is present based on the sensor data; and (iii) provide an indication to a user that an occupant is present using the HMI output device when it is determined that an occupant is present.

A vehicle alarm notification system including a housing having a plurality of directional indicia on a front side thereof. A wireless transceiver is operably connected to a power source disposed within the housing, wherein the transceiver can receive an alert signal from a vehicle alarm system when the vehicle alarm system is activated. A microprocessor is operably connected to the wireless transceiver. The microprocessor can determine a location of a vehicle, via an associated vehicle GPS, relative to a position of the housing. The microprocessor is further programmed to illuminate one of the plurality of directional indicia to indicate the location of the vehicle relative to the position of the housing when the alert signal is received. In some embodiments, a speaker is disposed within the housing, wherein the speaker can emit an audible alarm when the alert signal from a corresponding vehicle alarm system is received.

A detector, system and method for detecting vehicle lock status are provided. The detector comprises a motion sensor configured to sense vehicle door open and close movement; a microphone configured to record sound patterns generated with targeted events; a wireless communication module; a memory for storage; a battery for supplying power; and a controller connected to the motion sensor, microphone, wireless communication module, memory and battery respectively and configured to switch on or off the microphone and the wireless communication module according to signals provided by the motion sensor, and control the wireless communication module to transmit sound files wirelessly. The detector is designed and sized to be attached to the vehicle door. The detector is easy to use, easy to install, yet affordable for detecting the lock status of the vehicle and show the lock status on the driver's smart phone even if he/she has walked away.

Disclosed is a system for detecting an operating state of a vehicle engine. The system comprises: an input coupled to a power line of a vehicle; means to filter out relatively high frequency transient noise components of a signal received from the power line; a first detector for receiving the filtered signal and detecting when transient noise associated with the power line rises above a first threshold and generating a first detection signal in response thereto; a second detector for receiving the filtered signal and detecting when the transient noise falls below a second threshold, which is lower than the first threshold, and generating a second detection signal in response thereto; and means for generating a first output signal in response to the first detection signal and a second output signal in response to the second detection signal.

A system includes a first controller including a processor and a memory, and the memory stores instructions executable by the processor to receive first acceleration data from an accelerometer; upon determining that the first acceleration data satisfies a first criterion, transmit a wake-up instruction to a second controller; upon determining that the first acceleration data fails to satisfy the first criterion, instruct the accelerometer to send second acceleration data; and upon determining that the second acceleration data satisfies a second criterion, transmit the wake-up instruction to the second controller. The first criterion includes jerk exceeding a jerk threshold.

While a vehicle is in a minimal power state, a first sensor is activated based on a location of the vehicle within a monitored area. The vehicle is transitioned to an on state based on detecting an object via data from the first sensor. Then the vehicle is operated to block an exit from the monitored area based on identifying the object as an unauthorized object.

A detector, system and method for detecting vehicle lock status are provided. The detector comprises a motion sensor configured to sense vehicle door open and close movement; a microphone configured to record sound patterns generated with targeted events; a wireless communication module; a memory for storage; a battery for supplying power; and a controller connected to the motion sensor, microphone, wireless communication module, memory and battery respectively and configured to switch on or off the microphone and the wireless communication module according to signals provided by the motion sensor, and control the wireless communication module to transmit sound files wirelessly. The detector is designed and sized to be attached to the vehicle door. The detector is easy to use, easy to install, yet affordable for detecting the lock status of the vehicle and show the lock status on the driver's smart phone even if he/she has walked away.

An apparatus and method for controlling a vehicle lock and a vehicle may be provided. The apparatus may include a main control circuit and a switch lock execution component. The main control circuit may be configured to determine a movement speed of the vehicle when the vehicle is in an unlocked state and is moved illegally. The main control circuit may be also configured to power on the switch lock execution component and control the switch lock execution component to lock a vehicle lock when the movement speed is greater than zero and less than a preset threshold. The switch lock execution component may be configured to execute a locking operation under control of the main control circuit after the switch lock execution component is powered on. According to the present disclosure, when the vehicle is moved illegally and the movement speed of the vehicle is greater than zero and less than the preset threshold, then locking operation may be executed so as to reduce a probability of occurrence of a dangerous accident.

A security system circuit for a vehicle includes an electronic main control unit, at least one electronically operated switch, which is arranged on an input line of an electric load of the vehicle. Each electronically operated switch is controlled by the main control unit and is configured to switch between a connected configuration. The electronically operated switch allows electricity to flow through the input line between a main electric power source of the vehicle and the electric load, and a cutoff configuration, where said electronically operated switch prevents electricity from circulating through the input line between the main power source and said electric load, a safety switch, configured to be activated by a user of the vehicle. The safety switch is configured to control the main control unit, so that each electronically operated switch switches to its cutoff configuration when the safety switch is activated.
