Abstract
An electrified vehicle with a brake position sensor and a controller and a downhill driving control method for the electrified vehicle include the controller which is configured to determine whether a virtual brake-based control condition is satisfied and outputs a braking command based on a virtual brake signal generated based on a first threshold value when the virtual brake-based control condition is satisfied.
Claims15
A vehicle comprising
- a brake position sensor;
- a motor configured to perform regenerative braking;
- and
- a controller configured to:
- determine whether a preset virtual brake signal-based control condition is satisfied during downhill driving based on an inclination of a road in which the vehicle is driving in a driving direction, a brake pedal input value inputted through the brake position sensor, a first threshold value related to the brake pedal input value and determined based on the inclination, and a decreasing state of the brake pedal input value;
- generate a virtual brake signal based on the first threshold value, based on the virtual brake signal-based control condition being satisfied;
- output a braking command based on a value of the virtual brake signal;
- and
- control the motor to perform the regenerative braking based on the outputted braking command,
- wherein the controller is configured to correct the value of the virtual brake signal based on a second threshold value which is smaller than the first threshold value, based on the brake pedal input value being decreased to less than or equal to the second threshold value, while the braking command is outputted.

A downhill driving control method of a vehicle, the method comprising:
- determining, by a controller, whether a preset virtual brake signal-based control condition is satisfied during downhill driving based on an inclination of a road in which the vehicle is driving in a driving direction, a brake pedal input value measured through a brake position sensor, a first threshold value related to the brake pedal input value and determined based on the inclination, and a decreasing state of the brake pedal input value;
- generating, by the controller, a virtual brake signal based on the first threshold value based on the virtual brake-based control condition being satisfied;
- outputting, by the controller, a braking command based on a value of the virtual brake signal;
- controlling, by the controller, a motor of the vehicle to perform the regenerative braking based on the outputted braking command;
- and
- correcting, by the controller, the value of the virtual brake signal based on a second threshold value which is smaller than the first threshold value, based on the brake pedal input value being decreased to less than or equal to the second threshold value, while the braking command is outputted.
