Embodiment Construction

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

[0053] Such as figure 1 The vehicle speed control system based on the driver's 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 alarm module 6 .

[0054] Such as 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 minus 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 connected in series; one end of the main switch is connected to the connection point between resistor R1 and resistor ...

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, in particular to a vehicle 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 speed control is the limit control of the maximum speed, that is, the driver sets the maximum speed of the car, and controls the vehicle through the engine torque so that the vehicle cannot exceed the set maximum speed during driving. [0003] The limit control of the maximum speed can effectively prevent the occurrence of overspeed and has a positive effect. However, in the current situation, it has become an objective requirement for the driver to be able to flexibly control the vehicle speed, and only limiting the maximum speed can no longer meet the demand. [0004] Therefore, it is necessary to develop a new dr...
