Vehicle adaptive cruise control system and method capable of recognizing driving tendency

Abstract

The invention discloses a vehicle adaptive cruise control system and method capable of recognizing driving tendency. The vehicle adaptive cruise control system comprises a radar, a vehicle speed sensor, an ACC controller, an acceleration / deceleration execution device, a driving tendency recognizer and a driver identity recognizer. When the vehicle is driven manually, the driving tendency recognizer enters a driving tendency recognition working mode, calculates driving tendency coefficients of the driver and stores the driving tendency coefficients in one-to-one correspondence with driver identity information. When the vehicle is subjected to adaptive cruise driving, the driving tendency recognizer enters a driving tendency extraction working mode to extract a driving tendency coefficient corresponding to the current driver identity; and the ACC controller corrects the expected vehicle distance according to the driving tendency coefficient, so that the corrected expected vehicle distance conforms to the driving habit and psychological expectation of the current driver, and the method has the beneficial effect that the trust degree and the utilization rate of each driver to the adaptive cruise control system can be effectively improved.

Description

technical field [0001] The invention relates to a vehicle adaptive cruise control technology, in particular to an adaptive cruise control system that can identify the tendency of drivers and meet their psychological expectations and can improve trust, belonging to the field of automobile control systems. Background technique [0002] Adaptive Cruise Control (ACC) is an important part of Advanced Driving Assistant System (ADAS) and the basic technology for automatic driving. The perception system of ACC perceives the driving environment ahead, and the controller processes various input information, gives appropriate control amount, controls the throttle and braking system of the power unit, automatically adjusts the vehicle speed and distance, and realizes the longitudinal driving operation. automation. ACC frees the driver's feet, reduces driving labor intensity, and improves driving comfort and safety. At present, ACC has achieved great development, and a large number of ...

Problems solved by technology

Recently, some researchers have begun to consider the driver's personalized driving characteristics in the ACC system. The scheme adopted is to set several driving modes and provide them for manual selection by the driver. Driving habits and tendencies are identified and stored online, and the expected distance between vehicles cannot be automatically adjusted according to the current driver's driving tendency during automatic cruise driving, actively adapting to the psychological expectations of each driver's driving distance
