Problems solved by technology

With the advancement of technology and the improvement of automobile performance requirements, as one of the few units in the automobile that can perform human-computer information interaction, people hope that the accelerator pedal can realize more interactive functions; however, the ordinary accelerator pedal only serves as a single The role of information transmission, that is, the driver realizes the control intention of the car through the accelerator pedal, but the car cannot feed back the driving condition information to the driver through the accelerator pedal
And in the process of actual road driving, especially in the process of following a car on urban roads, different types of drivers tend to control the accelerator pedal differently, resulting in differences in the driving speed, following time distance, and braking behavior of the own vehicle. Makes a big difference in performance and fuel economy
Studies have shown that under the same driving conditions, aggressive drivers will step on a larger pedal depth, resulting in higher speed and shorter following distance, in order to avoid accidents, and then make more brakes Behavior; this kind of driving behavior is not only highly dangerous, but also causes huge waste of fuel and reduces the fuel economy of the car

Abstract

The invention discloses an intelligent man-machine interaction type vehicle accelerator pedal device. The device comprises a pedal rotary shaft system, a control shaft system, a sliding polished shaft system and a clutch shaft system. The pedal rotary shaft system, the control shaft system, the sliding polished shaft system and the clutch shaft system are arranged on a pedal support. The pedal rotary shaft system is used for achieving work states of a common accelerator pedal, the control shaft system transmits power to the clutch shaft system through the sliding polished shaft system, a cylindrical cam, idler wheels and a transmission rod in the clutch shaft system drive a pressing plate to move axially so that the plate-type cam of the control shaft system can achieve feedback control of pedal force after the pressing plate and a friction plate are combined and locked, and an adjusting mechanism in the sliding polished shaft system can adjust the axial position of a sliding gear so that the common accelerator pedal can work when a control motor fails. Besides, control of rotation speed and power of an engine and running speed can be achieved through the common accelerator pedal, running states and road condition information can be fed back to drivers through an accelerator pedal in a tactile feedback mode, man-machine interaction is achieved, and the drivers are assisted in improving driving behaviors.

Description

technical field [0001] The invention belongs to the technical field of automobile driving assistance systems, and specifically relates to an intelligent human-computer interactive automobile accelerator pedal device. technical background [0002] Accelerator pedal, also known as accelerator pedal, is a device for the driver to control the engine speed and driving speed of the car, and is one of the key accessories of the car. The traditional pull-wire accelerator pedal is still commonly used on freight vehicles today, and it is mainly composed of a pedal bracket, an accelerator pedal, a thin steel rope, and a return spring. The accelerator pedal is directly connected to the engine throttle by using a thin steel rope. The stepping depth corresponds to the opening of the solar terms 1:1. Therefore, the pull-wire accelerator pedal has a simple structure and direct control, but the control accuracy is low, and it cannot meet the needs of the current electronically controlled en...
