Embodiment Construction

[0094] The present invention is described in detail below in conjunction with accompanying drawing:

[0095] refer to figure 1 , a configuration diagram of an adaptive cruise system based on a pure electric vehicle with a traditional ABS (anti-lock brake system) provided by the present invention, which is a complete vehicle adaptive cruise system based on the existing components of the original vehicle design. The components of the adaptive cruise system include vehicle controller, drive motor controller, drive motor, battery management system, battery pack, original vehicle ABS controller, 4 wheel speed sensors, millimeter wave radar, ESC (body electronic stability control system) hydraulic adjustment unit, 4 wheel cylinder pressure sensors, dSPACE Micro Autobox controller (dSPACE company's rapid prototyping controller), dSPACE Rapid pro drive (dSPACE company's rapid prototyping drive).

[0096] For the existing components of the original vehicle, the components that have n...

Abstract

The invention belongs to the field of automobile driving assistance and relates to a self-adaptive cruising system and a control method. The self-adaptive cruising system comprises a whole automobile controller, a drive motor controller, a drive motor, a battery management system, a battery pack, an original automobile ABS controller, wheel speed sensors, millimeter-wave radar fixed to a whole automobile front bumper, wheel cylinder pressure sensors installed on brake pipelines in front of braking wheel cylinders, an ESC hydraulic adjusting unit, a dSPACE Micro Autobox controller and a dSPACE Rapid pro driver. Whether a whole automobile enters a self-adaptive cruising system active braking control state or not is judged according to the whole automobile traveling state; then, under the self-adaptive cruising system active braking control, the duty ratio of conversion valves is controlled to conduct wheel cylinder pressure control, and a response to the whole automobile target braking intensity is made; and the ESC hydraulic adjusting unit conducts initialized pressure reduction control. By the adoption of the self-adaptive cruising system and the control method, the quick prototype development technology is used, and earlier stage design and an active braking function of the self-adaptive cruising system of a blade electric vehicle are achieved.

Description

technical field [0001] The invention belongs to the field of automobile driving assistance, and in particular relates to an adaptive cruise system and a control method. Background technique [0002] In recent years, with the increase of car ownership, the incidence of traffic accidents has also increased day by day. The research and development of driver assistance systems has gradually attracted people's attention, among which adaptive cruise technology provides an effective solution to solve the problems of driving safety, driving comfort and traffic congestion. [0003] The adaptive cruise control system is an intelligent automatic control system that keeps a safe distance between the vehicle and the vehicle ahead by coordinating the vehicle distance and speed. The adaptive cruise system of a pure electric vehicle usually has a radar system, an adaptive cruise controller, and an active braking system. When the vehicle is in the adaptive cruise system, the adaptive cruis...
