Problems solved by technology
The invention discloses a car safety control method based on bidirectional speed measurement. The method includes the following steps that (1) a front distance measuring unit and a rear distance measuring unit are arranged on a car, the front distance measuring unit is used for measuring the distance S between the car and a car located in front in the driving direction of the car, and the rear distance measuring unit is used for measuring the distance S4 between the car and a car located behind in the direction opposite to the driving direction of the car, and the distances are transmitted to a control unit; (2) a speed measuring unit is arranged on the car, the speed measuring unit is used for measuring the relative speed V2 between the car and the car located in front in the driving direction of the car, and the relative speed V4 between the car and the car located behind in the direction opposite to the driving direction of the car, and the relative speeds are transmitted to the control unit; and (3) the control unit receives the information, outputs brake signals and controls the car to brake. The method can be used for conducting safe car anti-collision control in a short distance and is particularly suitable for an intelligent driving mode or an unmanned driving mode.
