Filed:

Mar 9, 2018

Appl. No.:

15/917429

Inventors:

- Gardena CA, US
Steven E. Schulz - Torrance CA, US
Michael Hong - Irvine CA, US
Anil Paryani - Cerritos CA, US
Isaac Benjamin Meadows - Los Angeles CA, US
Evan Roger Fischer - Torrance CA, US

International Classification:

B60L 50/60
H02J 7/00

Abstract:

The present disclosure relates to a vehicle power system. In some examples, the vehicle power system can include a plurality of redundant low-power buses coupled to respective low-power batteries. The low-power buses can be powered by a vehicle battery having a higher voltage than the voltage of the low-power batteries by way of a DCDC converter, for example. In some examples, the DCDC converter can be coupled to the low-power buses via a plurality of switches included in an Auxiliary Voltage Controller (AVC). The DCDC converter and the AVC can be housed in a common package to reduce the size, weight, and complexity of the power system while also improving the power system's durability.

Abstract:

A battery system of an electric vehicle is disclosed. The battery system can include at least a first battery string including a number of battery modules, wherein the first battery string has an output that is coupled to the first power bus through a string switch, and wherein each of battery modules includes a plurality of battery cells connected in series. The battery system can also include a number of battery module monitors, wherein each of the battery module monitors is coupled to the battery cells of a corresponding one of the battery modules. The battery system can further include module monitor protection circuitry coupled to each of the battery module monitors, wherein the module monitor protection circuitry includes a plurality of protection circuits.

Abstract:

A multi-processor architecture for automated driving systems can be used to improve performance and provide design flexibility. For example, a multi-processor architecture can be used to implement command generation and safety functionality in different processors. The command generation processor can be a high performing processor compared with the safety processor. The safety processor can verify the safety of commands output from the command generation processor and provide additional I/O channels that are typically absent on high performing processors. Additionally, processing of some sensor data can be moved to expansion modules with additional processors to reduce bottlenecks and provide design flexibility for systems with different sensing requirements.

Inventors:

- Gardena CA, US
Michael Hong - Gardena CA, US
Phillip John Weicker - Pasadena CA, US
Anil Paryani - Cerritos CA, US

International Classification:

B60L 11/18

Abstract:

Systems and methods for disengaging a battery are disclosed. The systems and methods may be used to disengage a battery from a direct-current (DC) bus of a vehicle when the DC bus is under a load. In one implementation, the system includes one or more contactors between the battery string and the DC bus. The system also includes a controller. The controller is configured to reduce a current limit of a power train of the vehicle to a first current level. The controller is also configured to open the one or more contactors. The controller is further configured to increase the current limit of the power train of the vehicle to a second current level.
