Working method of large vehicle steering active safety system

Abstract

The invention discloses a working method of a large-vehicle steering active safety system. The working method includes following steps: step 1, setting a wheel speed sensor to collect a current speed of a vehicle; step 2, setting a system ECU (electronic control unit) to acquire a vehicle speed signal from an anti-lock braking system (ABS) or a vehicle dynamic electronic stability program (ESP) through a CAN (controller area network) bus; step 3, setting a steering wheel steering angle sensor to collect a current angle of a steering wheel; step 4, setting the system ECU to acquire a current angle of the steering wheel from an electric power-assisted steering system (EPS) through a CAN bus; step 5, calculating a shortest transverse braking distance and a shortest longitudinal braking distance of the vehicle according to the current speed of the vehicle; step 6, acquiring a transverse safe distance between pedestrians or obstacles and the vehicle by adding the shortest transverse braking distance of the vehicle with a preset isolating distance. The working method is simple in structure and convenient to use, and traffic accidents are avoided.

Description

technical field [0001] The invention relates to a system working method, in particular to a working method of a large vehicle steering active safety system. Background technique [0002] Traffic accidents involving large trucks are not uncommon. In such accidents, both parties in the accident range from vehicle damage to casualties. In traffic accidents involving motor vehicles, the probability of accidents when the vehicle turns right is much higher than that of turning left and going straight. According to the principle of traffic on the right side, large vehicles tend to form mixed traffic with pedestrians, battery cars, bicycles, etc. when turning right, because the driver's blind spot and other road participants lack knowledge of the vehicle's inner wheel difference, accidents are prone to occur. In accidents involving large vehicles such as cement tankers, many drivers do not even know that the vehicle has been involved in an accident. Follow-up investigations showed...

Problems solved by technology

[0006] There are also some yellow sand trucks and large trucks with a height of more than 3 meters. Drivers at such a height can only see taller objects. If pedestrians or vehicles are too close to this blind spot, danger is very likely to occur.
