Embodiment Construction

[0036] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0037] The present invention provides a braking system driven by a servo mechanism. Through the mutual detection of two driving steering gears, the operating status of the two braking systems can be detected in real time. When one of them is abnormal, the other driving steering gear will trigger an emergency. Braking mode, and the present invention realizes the one-way transmission of the torque in the braking process through the design of the push block I on the outer edge of the steering gear output shaft and the push block II in the connecting rod and the output shaft matching hole, that is, it can only The torque is output from the brake steering gear, and the torque from the connecting rod to the brake steering gear cannot be transmitted, so that the driver can artificially step on the pedal to brake.

[0038] Such as figure 1 As shown, the present i...

Abstract

The invention provides a braking system used for a driverless vehicle and capable of switching driving modes. Through mutual detecting of two driving steering engines, operating states of two brakingsystems are detected in real time, and when one of the driving steering engines is abnormal, the other driving steering engine triggers the emergency braking mode; and through design of a pushing block I and a connecting rod at the outer edge of an output shaft of a steering engine and a pushing block II in a matching hole of the output shaft, one-way transmitting of torque in the braking processis achieved, that is, the torque only can be output through a braking steering engine, torque from the connecting rod to the braking steering engine cannot be transmitted, and thus a driver can manually step on a pedal to brake.

Description

technical field [0001] The invention belongs to the technical field of unmanned vehicles, and in particular relates to a braking system for an unmanned vehicle with switchable driving modes. Background technique [0002] Today, the development trend of the automobile industry is clean, lightweight and intelligent. With the continuous deepening of the intelligent development of vehicles, unmanned driving technology has attracted more and more people's attention and expectations. The design and control of the drive-by-wire chassis is one of the key technologies for unmanned vehicles. Compared with the traditional chassis, the control-by-wire chassis has the following advantages: the driving / steering / braking systems all adopt the control-by-wire technology, the structure of the chassis mechanical system is simpler, and the flexibility of the chassis layout is further improved; there is no need to consider the design of the driver's cockpit and operating mechanism; The chassis...
