Abstract

The invention discloses an opening degree detection method for a brake pedal of a hybrid electric vehicle. The method comprises the following steps of acquiring an opening degree analog quantity and a switching value signal of a brake pedal, wherein the switching value signal is used for driving a rear brake lamp; calibrating the opening degree analog quantity of the brake pedal by utilizing the switching value signal and identifying whether the brake pedal is stepped on; when the brake pedal is stepped on, matching the opening degree analog quantity of the brake pedal and a first reset section, if the opening degree analog quantity of the brake pedal is located in the first preset section, matching the opening degree analog quantity of the brake pedal with a second preset section; if the opening degree analog quantity of the brake pedal is located outside the second preset section, updating the opening degree analog quantity of the brake pedal; and calculating the opening degree value of the brake pedal according to the opening degree analog quantity of the brake pedal. The invention further discloses an opening degree detection device and a brake pedal device for the brake pedal of the hybrid electric vehicle; the safety coefficient of the brake pedal is improved, and the standard difficulty of the pedal is reduced.

Description

technical field [0001] The invention relates to the technical field of vehicle manufacturing, in particular to a brake pedal device, an opening detection method and an opening detection device for the brake pedal device. Background technique [0002] With the popularization of hybrid electric vehicles in people's life and work, the safety of hybrid electric vehicles has also received more and more attention. Brake pedal signal processing plays a vital role in the safety of the vehicle, and hybrid vehicles have certain differences from traditional vehicles in the processing of brake pedals due to their own characteristics. [0003] For hybrid vehicles with braking energy feedback function, the braking function is realized by two parts, one part is electric braking function, and this part of electric braking kinetic energy converts the energy generated by braking into electric energy storage through the braking force of the motor itself In the battery; the other part is the m...
