Problems solved by technology

However, when the inter-vehicle distance is large or the vehicle in front suddenly accelerates and decelerates, its control quality often declines.
The specific performance is that the vehicle has a large vibration, which causes the driver's discomfort and increases the fuel consumption of the vehicle; when the vehicle needs...

Embodiment Construction

[0020] The invention proposes an automobile self-adaptive cruising control system based on working conditions from the driver's point of view. The specific implementation steps and methods of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0021] Step 1: Use the radar installed on the front of the vehicle to detect whether there is a target vehicle within the effective distance ahead. If there is no target vehicle, it means that there is no vehicle. Relieve the driver's operating intensity, which belongs to the traditional cruise control system.

[0022] Step 2: Ensuring the absolute driving safety of the vehicle is the premise and key to the system's work. Therefore, when the radar detects that there is a target vehicle driving within the effective distance ahead, it is first necessary to judge the safety state of the vehicle, including: safe state, dangerous state and Very dangerous state, to improve reliable state in...

Abstract

The present invention relates to an automobile self-adaptive cruising and sub-working condition control system, which is characterized in that it includes an information collection unit, a state recognition unit, a control decision-making unit and a vehicle dynamics unit; the information collection unit collects driving state information and sends it to State recognition unit, the state recognition unit recognizes the safety state of the self-vehicle and the state of the forward target vehicle relative to the self-vehicle, and sends the recognition result to the control decision-making unit; the control decision-making unit analyzes the actual needs of the driver in each state, and Taking vehicle safety, followability, fuel economy and driver comfort as indicators, a multi-objective optimization problem is established, and the optimal controller is selected according to the state recognition results, and the optimal control acceleration is calculated and processed continuously. The results are sent to the vehicle dynamics unit; the vehicle dynamics unit converts the optimal control acceleration into the desired throttle opening or brake pressure, and realizes the multi-state and working-condition control of the vehicle.

Description

technical field [0001] The invention relates to an automobile driver assistance system, in particular to an automobile self-adaptive cruising control system according to working conditions. Background technique [0002] With the rapid development of the economy, automobiles have become an indispensable means of transportation for people's social life. The continuous increase in the number of automobiles has led to the trend of high-speed vehicles, non-professional drivers and intensive traffic flow in automobile traffic. The resulting frequent traffic accidents, road congestion, and energy waste have become increasingly prominent. Transportation presents great challenges. [0003] Automotive adaptive cruise control (Adaptive Cruise Control, ACC), as one of the key technologies of Advanced Driver Assistant System (ADAS), has become a research hotspot in the field of intelligent transportation at home and abroad. It can replace the driver to control the accelerator and brake...
