Embodiment Construction
[0027] The present invention predicts the response deceleration of the driver and calculates the safe distance value for the driver to avoid collision according to the kinematics theory under the hypothetical early warning reaction time value. When the actual distance between the front and rear vehicles is less than the safe distance, a Car driver warning information, to achieve forward collision avoidance warning function. The algorithm of the invention calculates the braking distance required for collision avoidance according to the actual vehicle motion state, and has higher accuracy and reliability compared with the danger perception algorithm. In addition, the algorithm allows the adjustment of parameter pairs such as driver reaction time and braking deceleration to take into account the characteristics of driver reaction differences.
[0028] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
