Embodiment 1

[0037] Such as figure 1 The illustrated embodiment is a cruise control system and control method. The car includes a chassis, a steering column, an integrated instrument panel, a speed sensor 2, a throttle and an electronic throttle actuator 6; the cruise control system includes an instruction Switch 1, slope sensor 3 and controller; command switch, speed sensor and slope sensor are connected with controller 5 respectively, controller is connected with electronic throttle actuator, and electronic throttle actuator is connected with engine throttle 7.

[0038] The slope sensor is arranged on the chassis of the car. The command switch includes a vehicle speed setting switch and a vehicle speed recovery switch arranged on the integrated instrument panel. The controller includes a storage unit storing control software.

[0039] The control method comprises the steps of:

[0040] (1) During the driving process of the car, the speed sensor and the slope sensor respectively detect...

Embodiment 2

[0050] Embodiment 2 includes the structural parts in Embodiment 1, and also includes that the steering column is provided with an angle sensor, and the angle sensor 4 is connected with the electronic control unit. The control method in Embodiment 2 includes all the steps in Embodiment 1, and each step in steps (3-1), (3-2) and (3-3) also includes the following steps:

[0051] During the driving process of the car, the angle sensor tests the rotation angle of the steering wheel of the car from the straight-line driving position of the car and transmits the angle data to the controller. ; The controller reduces the opening of the throttle through the electronic throttle actuator, and the speed of the car becomes 80% of the set speed within 10 seconds.

Abstract

The invention discloses a cruising constant-speed control system and a cruising constant-speed control method. A car comprises a car chassis, a steering pipe column, an integrated instrument platform, a speed sensor, a throttling valve and an electronic accelerator actuator; the cruising constant-speed control system is characterized by comprising an instruction switch, a gradient sensor and a controller; the instruction switch, the speed sensor and the gradient sensor are respectively connected with the controller, the controller is connected with the electronic accelerator actuator, and the electronic accelerator actuator is connected with the throttling valve of an engine. The cruising constant-speed control system has characteristics that the running speed of the car can be adjusted according to the road situation and the rotating angle of a steering wheel; the fuel can be economized; the engine is not easy to damage; drivers can easily concentrate and are not easy to fatigue; and reliable insurance can be provided for the safe driving.

Description

technical field [0001] The invention relates to the technical field of cruise control, in particular to a cruise control system and a control method capable of adjusting the driving speed of a vehicle according to road conditions. Background technique [0002] At present, there are more and more models with cruise function. This technology can free the driver's feet from the accelerator pedal and relieve the driver's fatigue from long-distance driving. [0003] Ordinary cruise control system keeps the car running at a constant speed all the way under different road conditions. Although this function brings a lot of convenience to the driver, there are also some disadvantages in this driving method. Once the speed drops on a hill climb, the vehicle will use maximum engine torque and perhaps downshift to avoid a stall. [0004] In addition, the ordinary cruise control system keeps the vehicle at a constant speed before going downhill, and the vehicle enters the downhill sect...
