Abstract
A number of variations are disclosed including a computer program product and method of modifying brake-to-steer brake pressure commands, based on brake temperature, in real time as well as to create temperature dependent powertrain control and temperature dependent brake cooling.
Claims19
A computer program product comprising instructions executable by an electronic processor to carry out actions, comprising:
- determining at least one brake-to-steer brake command;
- communicating at least one brake temperature input to a brake-to-steer adjustment function and at least one brake pressure to torque scalar function;
- generating an arbitrated brake temperature data by arbitrating the at least one brake temperature input;
- generating at least one brake derating scalar based on arbitrated brake temperature data via a brake-to-steer brake derating logic function;
- generating at least one brake pressure to torque scalar based on the at least one brake temperature input;

- and
- generating at least one modified brake-to-steer brake command.
