Activation locking and error stepping preventing integrated accelerator pedal and control method thereof

Abstract

The invention discloses an activation locking and error stepping preventing integrated accelerator pedal and a control method thereof. The activation locking and error stepping preventing integrated accelerator pedal comprises a base, a stepping part, an accelerator pedal position sensor and an accelerator pedal control unit. The stepping part is divided into an upper layer and a lower layer, a locking face plate on the upper layer covers a locking bottom plate on the lower layer, and according to the cooperative relationship, the upper layer and the lower layer relatively move or are fixed. According to an optimized moving assembly, a displacement flash sensor for detecting relative displacement between the locking face plate and the locking bottom plate is mounted in the locking bottom plate, and the accelerator pedal position sensor and the displacement flash sensor are electrically connected with the accelerator pedal control unit. When being shifted, the locking face plate makes relative opposite trend movement or lateral movement on the locking bottom plate to trigger the displacement flash sensor, the accelerator pedal control unit is activated, and free acceleration under the activation state is achieved; and otherwise, error stepping and invalid accelerating are judged, the function of feedback braking is implemented, the problem of pedal misuse is solved, and the active safety of a vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of automobile safety, in particular to an integrated activation lock preventing accidental depressing of an accelerator pedal and a control method thereof. Background technique [0002] From the traditional pull-wire accelerator pedal to the present, in addition to the progress of the electronic accelerator pedal due to the development of electronic technology, the improvement of the accelerator pedal has not yet found breakthrough results, let alone disruptive innovations, especially in safety application technology. Pedal misuse accidents occur again and again. Recent research and inventions mostly focus on radar detection, pedal force and pedal acceleration monitoring and other technologies to judge the passive safety measures of automatic braking. There are insufficient all-weather adaptability of radar, detection and reflection blind spots in depressions such as rivers, ponds, and ditches, and the safet...

AI Technical Summary

Problems solved by technology

However, if the pedal layout is changed, there will be other technical interference and conflicts, and the pedal layout of existing cars is the precipitation of history and technology, which is relatively mature, so the wrong step on the pedal has become a dilemma that continues to be difficult to solve.
