摘要： A vehicle includes an electric machine having a rotor and a stator, a resolver that measures a position of the rotor relative to the stator, and a controller. The controller, based on the position and a resolver offset, injects a first current having only a d-axis component into the electric machine, and responsive to detecting a first motion output of the electric machine being greater than a threshold, adjusts the resolver offset according to a magnitude and direction of the first motion output.

摘要： A hybrid electric vehicle includes an engine that can selectively provide drive torque to propel the vehicle. An electric machine also selectively provides drive torque. A differential transfers the torque to and amongst wheels. A planetary gearset is coupled to the engine and has a ring-gear for transmitting ring-gear-torque to the differential. A continuous torque transfer member operatively couples the ring-gear and the electric machine to the differential. At least one controller is configured to alter engine output based on a ring-gear-torque-threshold. This enables a desired torque to transfer through the continuous torque transfer member to the differential.

摘要： A vehicle system includes a vehicle component with a component temperature sensor, and a fluid circuit in fluid communication with the component and with a fluid temperature sensor. A controller is in communication with the component sensor and the fluid sensor. The controller is configured to, in response to a temperature difference between the component sensor and the fluid sensor being greater than a predetermined threshold value, output a flag or a diagnostic code indicative of a fluid level in the fluid circuit. A vehicle diagnostic method and a vehicle are also provided.

摘要： A vehicle includes a hybrid powertrain. The hybrid powertrain includes an engine and an electric machine. In response to a loss of controllability of the electric machine, a controller is programmed to operate the powertrain in a limited operating mode. In the limited operating mode, the powertrain is controlled so that a speed of the engine is within a speed range such that the electric machine generates a current to charge a traction battery. In response to a loss of communication with a power inverter that controls the electric machine, the powertrain is controlled so that the speed of the engine is within the speed range and the current flowing to the traction battery is monitored. If the current flow is above a threshold, then the limited operating mode is entered.

摘要： A vehicle includes an electric motor and an engine selectively coupled to the electric motor. The vehicle has an electric motor controller configured to, in response to (i) an absence of receiving a motor command signal within a predetermined time, (ii) a battery voltage being below a first threshold and (iii) a motor speed exceeding a second threshold, restrict operation of the electric motor to a limited operating mode and control the electric motor to generate a charging torque for a battery.

摘要： A vehicle charging system includes a charger configured to receive power form an external power source and a connector. The connector is configured to receive power from the charger and transmit the received power to a vehicle via a high-voltage cable. The cable is configured to connect the connector to a vehicle battery. Each of the charger and the connector includes a high voltage interlock loop (HVIL) configured to cause the charger to cease power transfer upon recognizing a predetermined voltage difference at a pair of ports of the HVIL.

摘要： An electrified vehicle includes an engine configured to selectively apply propulsive torque to wheels of a first axle of the vehicle, a first electric machine configured to selectively apply propulsive torque to the wheels of the first axle of the vehicle, a second electric machine configured to selectively apply propulsive torque to wheels of a second axle of the vehicle, a traction battery electrically coupled to the first and second electric machines, and a controller configured to control engine torque, first electric machine torque, and second electric machine torque to provide a driver demand torque at the wheels of the first and second axles. The controller allocates torque between the first and second electric machines based on associated combined losses of the first and second electric machines and maintaining the torque of the first and second electric machines in the same direction.

摘要： A method, implemented in one or more controllers in a vehicle, includes, in a presence of a propulsive demand of the vehicle that is driven by an engine and an electric machine, holding electric machine current at a predetermined magnitude and sweeping an angle, defined between a reference current and a reference Iq component, through a predetermined range. The method further includes operating the electric machine thereafter according to a resolver offset derived from a value of the angle corresponding to an Iq component crossing zero.

摘要： A vehicle includes a battery control module and a controller. The battery control module may be configured to issue at regular intervals a message indicative of an SOC of a battery. The controller may be configured to, in an absence of receiving the messages at the regular intervals while in a key-on state and a torque demand is present, restrict power flow between the battery and an electric powertrain to a limit that is based on a predicted SOC to provide limited propulsive force.
