Problems solved by technology
However, obstacles are not classified, and it is impossible to effectively distinguish whether obstacles affect safe starting. Some, such as roadside stone pillars, high curbs, road guardrails, small obstacles on the ground, etc., will be recognized as obstacles and cause the system to fail. Perform automatic start, affecting system accuracy

The invention discloses an adaptive cruise system starting safety control system and method. The system comprises a control unit, a middle-distance sensor, a short-distance sensor, a visual camera, apower control unit and a brake unit; the middle-distance sensor is used for sensing first obstacle information within a first set distance around a vehicle and sending the first obstacle information to the control unit; the short-distance sensor is used for sensing second obstacle information within a second set distance around the vehicle and sending the second obstacle information to the controlunit; the visual camera is used for reading a picture of a road ahead of the vehicle, obtaining obstacle classification information after image information is processed and sending the classificationinformation to the control unit; the control unit is used for controlling the actions of the power control unit and brake unit according to the first obstacle information, the second obstacle information and the classification information. The adaptive cruise system starting safety control system and method have the advantages that the recognition precision can be improved, and effective safe starting is ensured.
Description
technical field [0001] The invention relates to a car cruise system, in particular to an adaptive cruise system start safety control system and method. Background technique [0002] Adaptive cruise control (ACC) is to automatically control the acceleration and deceleration of the vehicle in the longitudinal direction according to the traffic conditions in the direction of the vehicle, so as to reduce the driver's operating burden. When there is no vehicle ahead or the vehicle ahead is far away, ACC can drive at the cruising speed set by the driver; when the vehicle ahead is close, ACC can automatically maintain relative distance to the vehicle ahead according to the following distance set by the driver. Distance; In addition, in the working state, ACC can follow the vehicle in front and gradually decelerate until it stops. If the vehicle in front stops for a short time (eg <3s), ACC can also automatically control the vehicle to follow the vehicle in front when the vehicle...
