  • Publication number: 20180050672
    Abstract: A vehicle is provided. The vehicle includes a vehicle system. The vehicle system includes a brake-by-wire portion, which also includes a controller. The controller can cause a forced coastdown of the vehicle. The forced coastdown includes performing analyzing conditions of the vehicle system to determine whether the vehicle is in a stable state and to determine an amount of energy available to the vehicle system and automatically applying the forced coastdown when the vehicle is not in the stable state and the amount of energy is less than or equal to a threshold for continued manual operation of the vehicle. The forced coastdown also includes utilizing brake pressure to reduce a speed of the vehicle.

  • Publication number: 20180043876
    Abstract: A vehicle is provided. The vehicle includes a brake-by-wire sub-system, which includes a controller. The controller receives a request to enter a service mode. In response to the request to enter the service mode, the controller determines whether a vehicle is in a stable state based on comparing at least one system condition against at least one threshold. When the vehicle is in the stable state, the controller causes the brake-by-wire sub-system to enter into the service mode. Further, the controller monitors the at least one system condition against predefined parameters to determine that the vehicle is maintaining the stable state while in the service mode.

  • Patent number: 8886432
    Abstract: A vehicle brake system and method that are designed to improve the driver braking experience by compensating for the effects that humidity and temperature can have on brake performance. According to one embodiment, the method determines if a braking event is underway and, if so, it measures humidity and brake temperature. With this information, the method is able to compensate for anticipated changes in the coefficient of friction (?) of one or more brake components, such as brake pads or rotors, and to provide a modified brake command signal accordingly.
