In general, techniques are described by which a computing system detects low-impact collisions. A computing system includes at least one processor and memory. The memory includes instructions that, when executed, cause the at least one processor to determine whether an object collided with a vehicle based on a comparison of data received from at least one motion sensor configured to measure at least an acceleration of the vehicle and data received from a plurality of level sensors, wherein each level sensor is configured to measure a relative position between a body of the vehicle and a respective wheel of a plurality of wheels of the vehicle. Execution of the instructions further causes the at least one processor to perform one or more actions in response to determining that the object collided with the vehicle.

The present invention relates to a system that is mounted on a mounting structure or chassis intended to protect the vehicles and their occupants. The system uses a main computer, high-precision radars, external airbag impellers, airbags that protect the vehicle and to some extent help its buoyancy, fluid sensors to detect the water limit that the vehicle can reach, and if these sensors are activated send a signal to the main computer that is responsible for activating air bag impellers, an inclinometer to detect the limit of inclination established in the vehicle and if the inclinometer detects an inclination that exceeds the limit established, this sends a signal to the main computer that is responsible for activating all the air bag impeller devices; and a monitor with signal transmitters to visualize in the state in which the system is located.

A computer implemented method for localizing an occupant within a vehicle includes identifying whether at least one occupant is present within the vehicle based on a signal of an ultrasonic sensor and determining information regarding an inclination of the vehicle based on at least one signal of an inclination sensor. Based on the information regarding inclination of the vehicle, it is determined whether an occupant is present in one of a plurality of predefined sections of the vehicle if the presence of at least one occupant within the vehicle is identified.

A vehicle safety device for detecting vehicle tilt automatically shuts-off power to an ignition system and fuel pump and summons emergency assistance using a bistable switch circuit that toggles between a first bistable switch position in response to a reset signal and a second bistable switch position in response to an alert signal. The safety device can remain in the bistable switch positions without a power source and employ an encrypted bi-directional protocol to summon emergency assistance and generate the reset signal without vehicle operator intervention.

The operator of a tractor is protected from injury or worse by deploying an air bag from the side of the tractor before the tractor's inclination angle relative to horizontal is less than a predetermined value below which the tractor will tip over.

A seat belt retractor which is mounted in a mounting space formed on a backrest of a seat installed in a vehicle and comprises a spindle module including webbing and a spindle having the webbing wound on the outer surface thereof, wherein the spindle is arranged along the longitudinal direction of the vehicle corresponding to the thickness direction of the backrest in the mounting space, such that by rotating the direction in which the spindle, on which the webbing is wound, is installed, the width in the longitudinal direction mounted on the backrest of the seat can be minimized, thereby making the retractor more slender.

Methods and systems for preventing serious injury or vehicle damage resulting from collisions between automotive vehicles and people, animals, or other objects are described. In some instances, the system may comprise an object detection system configured to detect a human prior to impact with an automotive vehicle comprising the object detection system, and further configured to send a first activation signal upon detection of the human; a first actuator attached to the automotive vehicle; and a protection plate operatively connected to the first actuator and mounted on a structural component of the automotive vehicle; where upon receipt of the first activation signal by the first actuator, the protection plate is deployed from a non-vertical orientation into a vertical orientation and is vertically-positioned between a level of a front bumper of the automotive vehicle and a surface on which the automotive vehicle is traveling.

A vehicle turn-over determination apparatus includes a turn-over sensor, a memory, a determination processor, and a road-surface detector. The turn-over sensor detects a value of a turn-over angle or a turn-over velocity of a vehicle. The determination processor performs the determination of the turn-over of the vehicle on the basis of the value detected by the turn-over sensor and the determination-threshold information held in the memory. The road-surface detector detects a road surface that is present in a traveling direction of the vehicle. The determination processor varies the determination-threshold information acquired from the memory in accordance with an inclination of the road surface detected by the road-surface detector, and thereby generates adjusted-threshold information adjusted in accordance with the inclination of the road surface. The determination processor compares the adjusted-threshold information and the detected value with each other, and thereby perform the determination of the turn-over of the vehicle.

A method for motorcycle accident detection and notification utilizes a wireless communication device and a motorcycle including an instrument system and an overturn detection system. The wireless communication device can be a portable wireless communication device carried by the motorcycle driver or a built-in wireless communication device of the motorcycle. The followings steps are executed. Obtain the motorcycle speeds and the corresponding time point data. Detect whether the motorcycle is overturned, and if affirmative, the overturn sensor sends out an overturning signal and then the instrument system, by comparing the differences between the speeds before and after the overturning signal is generated, determines whether an accident is to be notified. If affirmative, an accident signal is sent to the wireless communication device which will then send accident notification messages to emergency contact persons, thereby enabling them to inform the police and to rescue the motorcycle driver.
