Autonomous Drive Function Which Takes Driver Interventions into Consideration for a Motor Vehicle
A processor unit (3) is configured to execute an autonomous driving function of the motor vehicle (1) during a first instance such that the motor vehicle (1) travels autonomously based at least in part on the execution of the autonomous driving function. The processor unit (3) is further configured to store a driver intervention, the driver intervention being performed by a driver of the motor vehicle (1) during the first instance while the motor vehicle (1) travels autonomously based on the execution of the autonomous driving function. Additionally, the processor unit (3) is configured to execute the autonomous driving function during a second instance, subsequent to the first instance, based at least in part on the stored driver intervention such that the motor vehicle (1) travels autonomously based at least in part on the execution of the autonomous driving function according to the stored driver intervention.
HYBRID VEHICLE SPEED AND TORQUE CONTROL
Aspects of the present invention relate to a method and to a control system for controlling an electric traction motor of a vehicle, the control system comprising one or more controllers, wherein the control system is configured to: limit a rate of change of torque requested from the electric traction motor for changing speed towards a speed target, in dependence on a lash crossing protection rate limiter; and upon removal of the limit prior to the speed reaching the speed target, inhibit initial increase of a torque requested from the electric traction motor for changing speed towards the speed target.

METHOD FOR DETERMINING AN OPTIMIZED TORQUE DISTRIBUTION TO THE DRIVE WHEELS OF A ROAD VEHICLE AND RELATIVE ROAD VEHICLE
A method for determining an optimized torque distribution to the wheels of a road vehicle comprising the steps of determining a table of distribution of the torque between a front axle and a rear axle; determining a second table and a third table of distribution of the torque between a right wheel and a left wheel of the rear axle and of the front axle, respectively; detecting the current longitudinal dynamics; using the first, the second and the third table to determine a current value of the first, of the second and of the third distribution factor, respectively, based on the current longitudinal speed and on the current longitudinal acceleration of the road vehicle.
Method for Adapting a Biting Point of a Hydraulically Actuated Hybrid Disengaging Clutch
A method for adapting a biting point pressure of a hydraulically actuated hybrid disengaging clutch arranged in a hybrid drive train of a motor vehicle between an internal combustion engine and an electric machine includes step by step implementation during driving of the motor vehicle via a plurality of selected engagement operations of the hybrid disengaging clutch with a manipulation of a rapid filling routine. Proceeding from an initially stored biting point pressure, a setting pressure, which is reduced relative to a subsequent rapid filling routine, is incrementally increased step by step. An actual value, which is set in each case for a test parameter, is detected until the actual value corresponds to a setpoint value. A change in the transmission of torque of the hybrid disengaging clutch is derivable via the actual value.
