Embodiment Construction

[0020] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited thereto.

[0021] Such as figure 1 As shown, taking the high-box truck T and the smart car E as examples, the scene where the smart car E follows the high-box truck T to a road intersection is shown. Now describe in detail the calculation parameters involved in the present invention:

[0022] Orientation relationship: from left to right, smart car E, E' (E' is the critical position where the car E follows the high-box truck T, and the driver's line of sight is just blocked when the driver observes the traffic lights), high-box truck T, and the road Intersection traffic light L.

[0023] On-board equipment: The smart car E is equipped with three smart modules, namely the millimeter-wave radar R, the ...

Abstract

The invention discloses a method for preventing a vehicle from running a traffic light at an intersection by mistake under an intelligent driving assistance system. The method for preventing the vehicle from running the traffic light at the intersection by mistake under the intelligent driving assistance system comprises the steps of obtaining information of a vehicle running environment by usinga sensor; inputting the information into an ACC function control module so as to obtain a visual field angle alpha for actual judgement; if alpha is larger than or equal to 0, transmitting a positiveor negative accelerated speed request value to a communication module; if the alpha is less than 0, transmitting a negative accelerated speed request value to the communication module; and finally, enabling the communication module to transmit information of controlling a following distance to a vehicle body control unit. According to the method for preventing the vehicle from running the trafficlight at the intersection by mistake under the intelligent driving assistance system, the identification accuracy can be improved, it can be guaranteed that a driver can observe more traffic road condition information, and the risk of running the traffic light by mistake can be prevented.

Description

technical field [0001] The invention belongs to the field of driving assistance for intelligent vehicles, and in particular relates to a method for preventing an ACC vehicle from mistakenly running a red light at an intersection. Background technique [0002] Advanced Driver Assistance Systems (ADAS for short) have been popularized in vehicles driving on urban roads. Among them, adaptive cruise control technology (adaptive cruise control, ACC) is currently the most widely used driver assistance system. ACC technology can collect the distance and speed difference between the vehicle and the front vehicle in real time through the millimeter wave radar, and change or maintain the running state of the vehicle based on the built-in control logic without time difference. The vehicle-mounted intelligent binocular camera collects the color image pairs of vehicles and traffic lights in front through the binocular camera, and inputs them to the processing module Raspberry Pi to obtai...
