Device for recovering and disabling constant-speed cruising system

Abstract

The invention provides a reliably controlled device for recovering and disabling a constant-speed cruising system, which comprises a pedal fixing support and a pedal arm, wherein the pedal fixing support is provided with a bearing, one end of the pedal arm is arranged on a vehicle body through a rotating shaft of the pedal arm, and the other end of the pedal arm is movably arranged on the bearingof the pedal fixing support through a pedal shaft fixed on the end part of the other end per se; and the device is particularly characterized by further comprising an angle sensor for detecting the rotation angle of the pedal arm, and the output end of the angle sensor is connected with a controller used for controlling the work of the constant-speed cruising system. By utilizing the angle sensorto detect the rotation angle of the pedal arm and transmit the rotation degree to the controller in real time, the controller can rapidly acquire the driving destination of a driver so as to disable or recover constant-speed cruising, so that control failures caused by the reasons that the pedal does not reset in place, a brake switch contact is abraded or a brake switch gasket is abraded and thelike can be avoided, and the control is more reliable.

Description

technical field [0001] The invention belongs to the technical field of constant speed cruise control of automobiles, and in particular relates to a recovery and release device of a constant speed cruise system. Background technique [0002] Cruise control system (CRUISE CONTROL SYSTEM) is abbreviated as CCS, also known as cruise control device, speed control system, automatic driving system, etc. Its function is: after closing the switch at the speed required by the driver, it will automatically Keep the speed of the vehicle accurately, so that the vehicle can run at a fixed speed. With this device, the driver does not need to control the accelerator pedal when driving on the expressway for a long time, which reduces fatigue and reduces unnecessary speed changes. Save fuel. [0003] After the cruise control of an existing car is started, it is often necessary to use the brake pedal to release or restore the cruise control due to traffic conditions during driving. Generally,...

Problems solved by technology

[0003] After the cruise control of an existing car is started, it is often necessary to use the brake pedal to release or restore the cruise control due to traffic conditions during driving. Generally, the cruise control release recovery signal is integrated into the brake switch, and the brake pedal is used to release or resume the cruise control. The stroke of the switch generates signal control, but because the stroke of the switch is extremely short, and the vehicle's constant speed cruise requires high precision and sensitivity to the control signal, it is often caused by insufficient return of the pedal, wear of the brake switch contact or braking Due to the wear of the switch gasket and other reasons, the constant speed cruise cannot be released or restored, resulting in cruise control failure and EPC light always on
