Abstract
Disclosed are an emergency brake control method, device, ECU and vehicle. The method includes: when receiving a first trigger signal indicating that a vehicle enters a driving accompanying mode, activating the driving accompanying mode; and in the driving accompanying mode, when receiving an emergency brake command, controlling an Electronic Stability Program ESP to decelerate the vehicle at a preset deceleration in the driving accompanying mode, and sending a fuel cut-off request signal to an Engine Management System EMS to cut off a torque output of an engine.
Claims8
An emergency brake control method applied to a vehicle, comprising:
- in response to receiving a first trigger signal indicating that the vehicle enters a driving accompanying mode, activating the driving accompanying mode;
- and
- in the driving accompanying mode, in response to receiving an emergency brake command, controlling an Electronic Stability Program (ESP) to decelerate the vehicle at a preset deceleration in the driving accompanying mode, and sending a fuel cut-off request signal to an Engine Management System (EMS) to cut off a torque output of an engine;
- wherein in response to receiving the emergency brake command, the method further comprises:
- sending a request to change to a neutral gear to a Transmission Control Unit (TCU);
- and after the vehicle is braked to be stationary, controlling the Electronic Stability Program (ESP) to send a parking request to an Electronic Park Brake (EPB) system, to allow the Electronic Park Brake (EPB) system to perform parking brake.
An emergency brake control method deployed in a vehicle, comprising:
- an activating module configured to, when receiving a first trigger signal indicating that the vehicle enters a driving accompanying mode, activate the driving accompanying mode;
- and
- an emergency brake module configured to, in the driving accompanying mode, in response to receiving an emergency brake command, control an Electronic Stability Program (ESP) to decelerate the vehicle at a preset deceleration in the driving accompanying mode, and send a fuel cut-off request signal to an Engine Management System (EMS) to cut off a torque output of an engine;
- a gear change sending module configured to, send a request to change to a neutral gear to a Transmission Control Unit (TCU);
- and
- a parking request sending module configured to, after the vehicle is braked to be stationary, control the Electronic Stability Program (ESP) to send a parking request to an Electronic Park Brake (EPB) system, to allow the Electronic Park Brake (EPB) system to perform parking brake.
