Abstract:
A device includes at least one of a brake position sensor operationally coupled to a brake and providing a brake position signal, or a clutch position sensor operationally coupled to a clutch and providing a clutch position signal. The device further includes a controller having a communication module structured to interpret the at least one of the brake position signal or the clutch position signal, and a collection module structured to collect vehicle dynamics information. The controller further includes a vehicle dynamics module structured to interpret the vehicle dynamics information, and a sensor diagnostics module structured to determine a failure of at least one of the clutch position sensor or the brake position sensor in response to the vehicle dynamics information and at least one of the clutch signal or the brake signal.
Abstract:
A method for controlling the distribution of power to a traction motor in a plug-in electric vehicle having a plurality of on-board sources of electric power. Power is distributed at a normal power control relationship in response to an operator control input during operation in a normal mode. Power is depleted at a first rate during operation of the vehicle in the normal mode. Power is distributed at a derate power control relationship in response to the operator control input during operation in a derate mode. Power is depleted at a second rate that is less than the first rate during operation in the derate mode to conserve the power of the one or more on-board sources. Operation in the derate mode can be initiated in response to information from sensors identifying a vehicle condition indicating a battery charge limitation.
Abstract:
A climate control system for vehicles includes an internal combustion engine that may be coupled to selectively power a first motor generator, and an air conditioning compressor that may be selectively powered by one or both of the first motor generator and a second motor generator, or by the internal combustion engine. The system may include a rechargeable battery, and a vehicle controller having a vehicle state circuit structured to determine a vehicle operating condition value and a state-of-charge value of the rechargeable battery, and a coupling determination circuit structured to provide an internal combustion engine-first motor generator coupling command in response to the vehicle operating condition value and the state-of-charge value. In response to the internal combustion engine-first motor generator coupling command being provided as coupled, the internal combustion engine may power the first motor generator.
Abstract:
A method of controlling a vehicle accessory includes determining a transmission of a vehicle is in a non-park setting; in response to determining the transmission of the vehicle is in the non-park setting, receiving speed data indicative of a speed of the vehicle; determining a speed to operate the vehicle accessory based on the vehicle speed; comparing the determined speed to operate the vehicle accessory to a speed threshold; and in response to determining that the determined speed is below the speed threshold, providing a command to the vehicle accessory to one of deactivate the vehicle accessory or operate the vehicle accessory at a reduced operating state relative to a current operating state of the vehicle accessory.
Abstract:
An apparatus includes a route circuit and a stop-start circuit. The route circuit is structured to estimate a number of charging locations for an energy storage system of a vehicle for a planned route. The stop-start circuit is structured to determine a stop-start strategy for an engine of the vehicle based on the estimated number of charging locations and expected charges to be received by the energy storage system. The stop-start strategy defines a frequency and duration of using the engine in an on-mode during operation of the vehicle along the planned route. The stop-start circuit is further structured to determine that the energy storage system fails to receive an expected charge at one of the charging locations, and update the stop-start strategy to compensate for failing to receive the expected charge by increasing use of the engine in the on-mode during operation of the vehicle along the planned route.
