FIELD: machine building.
SUBSTANCE: proposed system for emergency braking of unmanned vehicles. Emergency braking system comprises working braking system and parking braking system. Emergency braking system is switched on at failure of power plant, at loss of connection of braking systems control unit with control unit of unmanned vehicle. Braking is performed with the help of working braking system, in case of failure - by parking braking system using autonomous power supply. Data on the current state of the unmanned vehicle and the service brake are transmitted to the unmanned vehicle control unit for subsequent transmission of said data to the brake system control unit. Braking system control unit receives wheel adhesion coefficient from the control unit. Braking strategy is also transmitted to braking system control unit. Braking strategy is calculated based on data on type of road surface and weather conditions. Braking strategy is to change braking force generated by working or parking brake system in time from the moment of braking to complete stop of unmanned vehicle. When forming the braking strategy, the parking brake takes into account the vehicle weight and the road grade. Weight is calculated based on acceleration and electric power. Road gradient is recorded on cartographic data and car inclination sensor.
EFFECT: higher safety is achieved.
