A vehicle includes first loads, a power source, and a processor coupled to the power source. Each of the first loads is configured to generate a fault signal indicative of an occurrence of an action performed by said first load to mitigate a voltage transient event. The processor is configured to, in response to a second different load being electrically coupled to the power source: control a voltage available within the power source based on calibration parameters; and in response to receiving the fault signal, adjust at least one of the calibration parameters.

System and method of adaptive high voltage transient control for external loads

System and method are disclosed for power management in a vehicle having two or more alternators. An example vehicle power system includes first and second alternators, and a processor. The processor is configured to determine that a load coupled to the first and second alternators increases at greater than a threshold rate. The processor is also configured to responsively (i) reduce respective voltage setpoints of the first and second alternators, and (ii) turn off the second alternator. And the processor is further configured to, after determining that a voltage transient caused by the load has expired, turn on the second alternator.

Dual alternator vehicle power management

A controller can display via an instrument cluster a brake capacity based on a temperature of friction material of at least one brake of a vehicle and a predicted brake fade threshold that is derived from a speed, mass, and current angle of inclination of the vehicle.

Brake fade and brake capacity gauge

A cruise control system for a vehicle includes a controller configured to maintain a speed of the vehicle about a setpoint, and in response to predicted brake capacity falling below a threshold based on predicted brake fade, reduce the setpoint and downshift a transmission of the vehicle to increase negative torque to reduce brake fade. Also, a powertrain of a vehicle includes an engine, an automatic transmission coupled with the engine, and a controller. The controller is configured to maintain a speed of the vehicle about a setpoint, and in response to a predicted brake capacity falling below a threshold based on predicted brake fade, reduce the setpoint and downshift the transmission to increase a negative torque.

Brake fade and brake capacity based powertrain operation

Methods and systems are provided for detecting hydrocarbon ingestion into an engine based on the simultaneous monitoring of cylinder imbalance and an elevated exhaust exotherm. Crankshaft acceleration data is monitored during steady-state and transient engine conditions while exhaust temperatures are estimated during non-regeneration conditions. Engine speed and load is limited to reduce further hydrocarbon ingestion.
