Abstract
A brake torque bias control system for a host vehicle is disclosed. The brake torque bias control system includes: devices configured to generate signals; and a control module configured, based on the signals, to bias a first amount of brake torque applied to a first side of the host vehicle to be greater than a second amount of brake torque applied to a second side of the host vehicle.
Claims20
A brake torque bias control system for a host vehicle, the brake torque bias control system comprising:
- a plurality of devices configured to generate a plurality of signals, wherein the plurality of devices comprise a plurality of paddle shifters;
- and
- a control module configured, based on the plurality of signals, to bias a first amount of brake torque applied to a first side of the host vehicle to be greater than a second amount of brake torque applied to a second side of the host vehicle, wherein the control module is configured to adjust an amount of brake torque biasing on a left side or a right side of the host vehicle based on inputs from the plurality of paddle shifters.
A brake torque bias control method comprising:
- generating a plurality of signals via a plurality of devices of a host vehicle;
- based on the plurality of signals, biasing a first amount of brake torque applied to a first side of the host vehicle to be greater than a second amount of brake torque applied to a second side of the host vehicle;
- obtaining one or more target parameters and a plurality of status parameters;
- determining, based on the one or more target parameters and the plurality of status parameters, the first amount of brake torque and the second amount of brake torque;
- evaluate whether a vehicle response is converging towards satisfying the one or more target parameters;
- based on evaluation of the vehicle response, executing a machine learning algorithm to adjust weighting of the plurality of status parameters;
- and
- based on the adjusted weighting, applying an updated first amount of brake torque on the first side of the host vehicle and an updated second amount of brake torque on the second side of the host vehicle.

- based on the plurality of signals, biasing a first amount of brake torque applied to a first side of the host vehicle to be greater than a second amount of brake torque applied to a second side of the host vehicle;
- determining the first amount of brake torque and the second amount of brake torque based on a plurality of status parameters,
- wherein the plurality of status parameters comprise a yaw angle of the host vehicle, a yaw rate of the host vehicle, an understeer value of the host vehicle, and a speed of the host vehicle;
- based on changes in the plurality of status parameters due to application of the first amount of brake torque and the second amount of brake torque, evaluating whether a vehicle response is converging towards satisfying one or more target parameters;
- based on evaluation of the vehicle response, executing a machine learning algorithm to adjust weighting of the plurality of status parameters;
- and
- based on the adjusted weighting, applying an updated first amount of brake torque on the first side of the host vehicle and an updated second amount of brake torque on the second side of the host vehicle.
