Abstract
A vehicle includes a high-voltage (HV) bus and a controller. The controller, during assembly of a control system including a plurality of HV devices to be installed in a predefined order such that one of the HV devices is installed before an other of the HV devices, and responsive to detecting presence of the other of the HV devices and absence of the one of the HV devices, disconnects a traction battery from the HV bus.
Claims16
A vehicle comprising:
- an in-vehicle communication network;
- a high-voltage (HV) bus;
- a traction battery;
- a control system including a plurality of HV devices;
- and
- a controller programmed to,
- during installation of the control system, responsive to detecting presence of one of the HV devices via one of the in-vehicle communication network or the HV bus, and detecting absence of the one of the HV devices via the other of the in-vehicle communication network or the HV bus, disconnect the traction battery from the HV bus, and
- during operation of the vehicle, responsive to detecting presence of the one of the HV devices via one of the in-vehicle communication network or the HV bus, and detecting absence of the one of the HV devices via the other of the in-vehicle communication network or the HV bus, not disconnect the traction battery from the HV bus.
A method for controlling a vehicle during an assembly process having multiple stages in which a first high-voltage (HV) device is installed during a first of the stages and a second HV device is installed during a second of the stages after the first of the stages, comprising:
- responsive to detecting, via a controller, a traction battery has been installed, connecting via a contactor the traction battery to a high-voltage (HV) bus;
- and
- responsive to detecting, via the controller, presence of the second HV device during the first of the stages, disconnect the traction battery from the HV bus.
A vehicle comprising:
- a high-voltage (HV) bus;
- and
- a controller programmed to, during assembly of a control system including a plurality of HV devices to be installed in a predefined order such that one of the HV devices is installed before an other of the HV devices, and responsive to detecting presence of the other of the HV devices and absence of the one of the HV devices, disconnect a traction battery from the HV bus.
