Embodiment Construction

[0019] The present invention comprises the vehicle speed sensor 15 that is connected with CAN bus and the steering wheel angle sensor 16, is connected with CAN bus and receives the controller 14 of the information gathered by vehicle speed sensor 15 and steering wheel angle sensor 16, is also connected with the output end of controller 14 Electric motor 17 , transmission 18 and headlight 19 with lidar detector 20 . According to the steering follow-up function of the AFS, when the lights turn as the steering wheel turns, the detection direction of the lidar detector 20 rotates synchronously with the headlights to detect the obstacle distance on the curve. This system is made up of electric motor 17, transmission mechanism 18, headlight 19 and lidar detector 20, vehicle speed sensor 15, steering wheel angle sensor 16 and controller 14. The controller 14 calculates the direction the driver expects to observe according to the vehicle speed and the steering wheel angle, and then co...

Abstract

The invention discloses a laser radar detection system based on AFS. The laser radar detection system is characterized in that according to the radar detection system, a controller is connected with a vehicle speed sensor and a steering-wheel rotation angle sensor through a CAN bus, so as to receive vehicle speed signal and steering-wheel rotation angle signal; the output end of the controller is connected with a motor and a transmission mechanism; the transmission mechanism drives a front big lamp of the laser radar detector; the detection direction of the laser radar detector can rotate synchronously with the front big lamp, so that the distance from an obstacle on the road can be detected. Through the above structure, the laser radar detection system, provided by the invention, can be used as an auxiliary facility for AFS, can eliminate visual dead spot of AFS, can discover the obstacle in a corner in advance to ensure safety; the overall manufacturing cost is low, and the laser radar detection system is suitable for popularization on middle level and low level automobiles.

Description

technical field [0001] The invention relates to the field of automobile driving safety control, in particular to an AFS-based laser radar detection system. Background technique [0002] AFS is also called Adaptive Steering Headlight System. It can continuously dynamically adjust the headlights according to the steering wheel angle, vehicle deflection rate and driving speed, adapt to the current steering angle, and keep the light direction consistent with the current driving direction of the car. To ensure the best lighting for the road ahead and the best visibility for the driver, it can automatically adjust the deflection of the headlights according to the driving speed, steering angle, etc., so that the "unreached" area can be illuminated in advance, providing all-round safety lighting, thereby significantly enhancing the safety of driving in the dark. In road conditions with no (weak) lights or many curves on the road surface, the driver's field of vision can be expanded...
