Problems solved by technology

[0003] However, most of the current adaptive cruise solutions in the field of commercial vehicles have disadvantages: 1. The function switching coordination problem between constant speed cruise control and adaptive cruise control has not been solved, and the switching of the two functions in the use state cannot be realized; 2. , Most of the engine ECUs of OEMs are outsourced, the software development cost is high, and the function decoupling is poor

Embodiment Construction

[0028] An embodiment of the present invention provides an adaptive cruise control system based on constant speed cruise. Through the settings of the adaptive cruise follower module and the constant speed cruise control module, an engine speed signal is sent to the engine according to the engine speed demand of the adaptive cruise mode or the constant speed cruise mode. The control command, on the basis of the constant speed cruise, cooperates with the adaptive cruise follow control module to realize the adaptive cruise function, realizes the switching between the constant speed cruise and the adaptive cruise, and effectively reduces the speed of the constant speed cruise and the adaptive cruise. The corresponding software development costs. Correspondingly, the embodiment of the present invention also provides a constant-speed cruise-based adaptive cruise control method, when switching from constant-speed cruise to adaptive cruise control, the current vehicle speed is set as th...

Abstract

The invention discloses a self-adaptive cruise control system and method based on cruise control, and relates to the field of auxiliary driving and whole vehicle electric control systems.The system comprises a self-adaptive cruise following module, a cruise control module and an engine power control module. The self-adaptive cruise following module is used for identifying an environment vehicle, making a front vehicle following control decision and processing a self-adaptive cruise control instruction sent by a driver. The constant-speed cruise control module is used for processing a constant-speed cruise control instruction sent by a driver and switching a self-adaptive cruise mode and a constant-speed cruise mode; and the engine power control module is used for sending a control instruction to an engine according to the engine rotating speed requirement of the self-adaptive cruise mode or the constant-speed cruise mode. According to the invention, switching between two use states of constant-speed cruise and self-adaptive cruise can be realized, and the software development cost corresponding to the constant-speed cruise and the self-adaptive cruise is effectively reduced.

Description

technical field [0001] The invention relates to the field of auxiliary driving and vehicle electronic control systems, in particular to an adaptive cruise control system and method based on constant speed cruise. Background technique [0002] At present, the adaptive cruise control scheme of automobiles is mainly divided into two parts: adaptive cruise follow control strategy based on millimeter-wave radar and vehicle longitudinal power control. The following two methods are adopted: 1. ACC (Adaptive Cruise Control, adaptive cruise control) integration of adaptive cruise controllers, that is, the adaptive cruise follow-up control strategy based on millimeter-wave radar is realized by the same controller, and the longitudinal power control of the vehicle adopts The TSC1 message defined in the SAE-J1939 protocol controls the engine speed. In the overall architecture, only the ACC integrates the controller and the engine ECU (Electronic Control Unit, Electronic Control Unit). T...
