Aspects of the present invention relate to a control system 12, method 400 and computer program 31 for controlling torque provided by a belt integrated starter generator 14 of a vehicle 10, the control system 12 comprising one or more electronic controllers 18, the one or more electronic controllers configured to: determine a change in torque to be provided by the belt integrated starter generator 14 according to a torque request 54; determine that the change in torque will cause the belt integrated starter generator 14 to enter a torque reversal region 51; and generate and output to the belt integrated starter generator 14 an altered torque request 56 within the torque reversal region 51, wherein the altered torque request 56 is generated and output to the belt integrated starter generator 14 when the torque request 54 would result in a reduction in the amount of torque provided by the belt integrated starter generator and when the torque request would result in an increase in the amount of torque provided by the belt integrated starter generator.

A vehicle is operable in three modes of operation. The vehicle includes a first electromagnetic device, a second electromagnetic device electrically coupled to the first electromagnetic device, and an engine coupled to the first electromagnetic device and configured to drive the first electromagnetic device to provide electrical energy. In each of the three modes of operation, whenever the engine drives the first electromagnetic device to provide the electrical energy, the first electromagnetic device operates without providing the electrical energy to an energy storage device.

Vehicles may be composed of a relatively few number of “modules” that are assembled together during a final assembly process. An example vehicle may include a body module, a first drive module coupled to a first end of the body module, and a second drive module coupled to a second end of the body module. One or both of the drive modules may include a pair of wheels, a battery, an electric drive motor, and/or a heating ventilation and air conditioning (HVAC) system. One or both of the drive modules may also include a crash structure to absorb impacts. If a component of a drive module fails or is damaged, the drive module can be quickly and easily replaced with a new drive module, minimizing vehicle down time.

A system and method for power management of hybrid electric vehicles is provided. In some implementations, a plug-in series hybrid electric vehicle may include an engine, a motor/generator (MG), a traction motor, an energy storage device, and a controller. The controller is coupled to the engine and the MG to control operation of the engine and the MG such that a state-of-charge (SOC) of the energy storage device tracks a dynamic reference SOC profile during a trip and an average engine power (AEP) is maintained above a threshold. In some instances, maintaining AEP above a threshold supports emission control of the vehicle.

The braking force control device detects an impossible state where one or some of the actuators are temporarily unable to generate a negative driving force, and a predictive state where one or some of the actuators are predicted to become unable to generate a negative driving force. Every time the coasting state occurs before establishment of the impossible state and after establishment of the predictive state, the braking force control device gradually increases the negative driving force generated by the corresponding one or ones of the actuators. Even when the coasting state occurs in the impossible state, the braking force control device does not cause the corresponding one or ones of the actuators to generate a driving force. Every time the coasting state occurs after the impossible state, the braking force control device gradually decreases the negative driving force generated by the corresponding one or ones of the actuators.

A braking force controller causes a first actuator unit to generate a target jerk when the target jerk is equal to or larger than a first jerk, causes the first actuator unit to generate the first jerk and a second actuator unit to generate a jerk obtained by subtracting the first jerk from the target jerk as an additional jerk when the target jerk is smaller than the first jerk and equal to or larger than the sum of the first jerk and a second jerk, and causes the first actuator unit to generate the first jerk and the second actuator unit to generate the second jerk as the additional jerk when the target jerk is smaller than the sum of the first jerk and the second jerk.

A vehicle communication system includes: a communication server and a vehicle control device. The vehicle control device (102) includes at least one electronic control unit configured to: recognize a position of the host vehicle; acquire section information on the communication established section and the communication interrupted section; determine in which section, either the communication established section or the communication interrupted section, the host vehicle is traveling or is to travel; perform system driven control of the host vehicle based on the road condition information when the host vehicle travels in the communication established section; and perform driver driven control of the host vehicle when the host vehicle travels in the communication interrupted section.

An electrified fire fighting vehicle includes a chassis, a cab coupled to the chassis, a body coupled to the chassis, a front axle coupled to the chassis, a rear axle coupled to the chassis, a water tank supported by the chassis, an energy storage system coupled to the chassis and positioned rearward of the cab, a water pump supported by the chassis, and an electromagnetic device electrically coupled to the energy storage system. The electromagnetic device is coupled to the water pump and at least one of the front axle or the rear axle. The electromagnetic device is configured to receive stored energy from the energy storage system and provide a mechanical output to selectively drive the water pump and the at least one of the front axle or the rear axle.

A driving assistance apparatus includes a clutch provided between a drive source and a transmission, a clutch operator with which a driver who drives a vehicle disengages the clutch, a clutch operation detector that detects that the clutch is disengaged, a shift operator with which the driver sets the transmission at least to a neutral position, a shift position detector that detects that the transmission is in the neutral position, a low-speed motor, and a controller that controls a drive force of the low-speed motor. The controller includes a driving mode setter that sets a driving mode of the vehicle to a motor driving mode when the clutch is detected to be disengaged or the transmission is detected to be in the neutral position. The controller stops the drive source and starts the low-speed motor when the driving mode is set to the motor driving mode.

The vehicle control method can include: determining a vehicle state based on a set of vehicle state inputs; determining a command based on the vehicle state; and controlling the vehicle according to the command. The method can optionally include updating a vehicle model based on a control outcome. However, the method S100 can additionally or alternatively include any other suitable elements. The method can function to determine longitudinal vehicle control based on a set of vehicle state inputs (e.g., a limited set of inputs—such as without direct knowledge of a throttle input, etc.). Additionally or alternatively, the vehicle control method can function to infer driving intent based on vehicle state measurements and/or translate inferred driving intent into low-latency vehicle control. Additionally or alternatively, the system can function to autonomously augment longitudinal propulsion, autonomously augment vehicle braking, and/or facilitate autonomous (longitudinal) vehicle control.
