Deadband

Notes in Slack from: Faraz Khan [12 days ago]
@etendue the way im using this is a happy place for the PID controller to go to when it goes negative. So let the PID controller vary from -1 to 1 but in the range -0.2 to 0 (which we'll call deadband) we just apply 0 throttle and brake and let the car coast (since engine/world braking would slow the car down anyways). This helps prevent extremely jerky flip flopping of gas-brake

If you are calculating the acceleration of the car that’s what you will use to compute the torque (torque = mass * accel * wheel radius). But if the acceleration is in the deadband, you make the torque zero

https://www.google.com/patents/US20060001314 also makes reference to deadband: "the brake pedal further comprises a connector for connecting the brake pedal to the friction brake system, the connector defines the deadband range wherein brake pedal displacement is not transmitted to the friction brake system, and a second range outside the deadband range wherein brake pedal displacement is transmitted to the friction brake system."
