Systems and methods are provided for controlling a hybrid powertrain of a hybrid vehicle, and may include: determining a value of a drive request for a combustion engine of the hybrid vehicle; determining electrical loading on batteries of the hybrid vehicle; adjusting operation of an accessory of the hybrid vehicle to reduce the electrical load of that accessory on the batteries of the hybrid vehicle when the drive request value is above a determined drive request threshold amount and the electrical loading on batteries of the hybrid vehicle is above a power loading threshold; and directing at least some of the power saved by adjusting operation of the accessory from the batteries of the hybrid vehicle to a drive motor of the hybrid vehicle to provide motive force for the vehicle.

An apparatus of starting an engine for a hybrid vehicle may include an engine configured for generating power by combustion of a fuel; a starting motor configured for starting the engine; a hybrid starter-generator configured for starting the engine, selectively operating as a generator, and selectively operating as a torque auxiliary device of a drive motor; and a controller configured for selectively performing a first starting mode to start the engine using the hybrid starter-generator according to a coolant temperature, a second starting mode to start the engine using the starting motor, and a third starting mode to start the engine using the starting motor and the hybrid starter-generator according to the coolant temperature.

A drive force control apparatus includes a drive force control section that has a steady drive force, a filtered drive force obtained by performing a filtering process on the steady drive force, and an internal drive force, which is calculated from a traction requested drive force, input thereto, and sets a target drive force based on the steady drive force, the filtered drive force, and the internal drive force. The drive force control section implements post-operation processing after control for causing the internal drive force to be the target drive force ends. In the post-operation processing, a new internal drive force, which is calculated based on a large-small relationship among the steady drive force, the filtered drive force, and the previously calculated internal drive force, is set as the target drive force.

A method for performing rotational speed synchronisation of a first transmission component having a first initial rotational speed with a second transmission component having a second initial rotational speed, so that they rotate with the same final rotational speed during a gear switch from an initial driving gear to a final driving gear in a stepped gear transmission for a hybrid electric or electric drive train having an electric traction motor. The method including calculating a total frictional work resulting from performing the total rotational speed synchronisation by means of a mechanical synchroniser of the stepped gear transmission only, and if the calculated total frictional work exceeds a maximal frictional work of the mechanical synchroniser, performing the rotational speed synchronisation by means of both the electric traction motor and the mechanical synchroniser.

In one example, a method may include determining a vehicle speed and a plurality of clutch position settings at a diagnostic controller, and identifying unauthorized conditions based on these determinations. Further, the diagnostic controller may trigger an active fault state of the mechanical vehicle component in order to avoid unauthorized conditions that may lead to unwanted or unanticipated changes in vehicle motion.

Various embodiments include a driver assistance system for determining the position of a stopping point of a vehicle at an infrastructure device comprising: a control unit; a communication device for receiving data from a server or from the infrastructure device; and a sensor arrangement for capturing vehicle data or environmental data. The control unit determines the location of the stopping point at the infrastructure device based at least in part on the data and the vehicle data or environmental data.

An example apparatus disclosed herein instructions, at least one memory, a processor to execute the instructions to operate a first brake of a first wheel of a vehicle, operate a second brake of a second wheel of the vehicle, determine a frictional coefficient of a driving surface of the vehicle by rotating a third wheel of the vehicle, determine based on the frictional coefficient, if a turn command can be conducted by the vehicle, and when the turn command can be conducted, conduct the turn command.

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.

A vehicle control device is configured to cause a vehicle to travel in a first mode when an enlargement mode is set, a driving force required for traveling of the vehicle is less than a value, and a capacity of a power storage is equal to or more than a first threshold, operate an internal combustion engine to cause the vehicle to travel in a second mode in response to the driving force becoming equal to or larger than the value when the enlargement mode is set and the vehicle is caused to travel in the first mode, and continue the enlargement mode when the capacity at a time when the driving force becomes equal to or more than the value is equal to or larger than a second threshold larger than the first threshold, and cancel the enlargement mode when the capacity is less than the second threshold.
