Embodiment Construction

[0052] The present invention will be further described below in conjunction with the accompanying drawings.

[0053] like figure 1 The shown vehicle speed control system based on driver operation includes a switch module 1 , an engine management module 2 , a vehicle speed control mode control module 3 , a vehicle speed setting module 4 , a vehicle speed control module 5 and an overspeed warning module 6 .

[0054] like figure 2As shown, the switch module 1 includes a resistor network and four switches coupled to the resistor network, the four switches are respectively the main switch (ASL Main), the vehicle speed control plus switch (RES / +), the activation / vehicle speed control reduction switch switch (SET / -), vehicle speed control cancel switch (Cancel). The resistor network is composed of resistor R1, resistor R2, resistor R3, resistor R4, resistor R5, and resistor R6 in series; one end of the main switch is connected to the connection point between resistor R1 and resist...

Abstract

The invention discloses a vehicle running speed control system and method based on driver operation. The system comprises a switching module, an engine management module connected with the switching module, a vehicle speed control mode control module connected with the engine management module, a vehicle speed setting module connected with the vehicle speed control mode control module, a vehicle speed control module connected with the vehicle speed setting module and an overspeed alarm module connected with the vehicle speed control module. In the activated mode, engine torque control is performed according to the set target vehicle speed, the vehicle speed is controlled to be near the target vehicle speed, and when the actual vehicle speed is larger than or equal to a set vehicle speed threshold value, an alarm is given; when the enabled condition of the KICK DOWN node is met, the system enters the KICK DOWN mode, the vehicle speed is allowed to be larger than the set target speed, and when the enabled condition of the KICK DOWN mode is not met, the KICK DOWN mode is automatically switched back to the activated mode. Flexible vehicle speed control is achieved, and different requirements of a driver can be met.

Description

technical field [0001] The invention belongs to the automobile engine control technology, and in particular relates to a vehicle traveling speed control system and method based on the driver's operation. Background technique [0002] The current complex road conditions and frequent traffic accidents have put forward higher requirements for vehicle speed control. Most of the existing vehicle speed control is the limit control of the maximum vehicle speed, that is, the driver sets the maximum running speed of the vehicle, and controls the vehicle not to exceed the set maximum vehicle speed during the driving process through the engine torque. [0003] The maximum speed limit control can effectively prevent the occurrence of overspeed and has a positive effect. However, in the current situation, it has become an objective need for the driver to flexibly control the speed of the vehicle, and only limiting the maximum speed can no longer meet the demand. [0004] Therefore, it ...
