ESTIMATION OF VEHICLE SPEED IN ALL-WHEEL-DRIVE VEHICLE

A vehicle includes an all-wheel-drive powertrain having an electric machine configured to power wheels. A controller is programmed to output a first calculated vehicle speed derived from integrating a measured longitudinal acceleration of the vehicle and output a second calculated vehicle speed based on the measured longitudinal acceleration and a speed of one of the wheels. The controller is further programmed to, responsive to a flag being present, command a speed to the electric machine that is based on the first vehicle speed to reduce wheel slip, and responsive to a flag not being present, command a speed to the electric machine that is based on the second vehicle speed to reduce wheel slip.

Apparatus for controlling autonomous driving of a vehicle, system having the same and method thereof

An autonomous driving control apparatus for a vehicle includes: a processor that determines whether a current driving condition of the vehicle is a limit situation during an autonomous driving control, performs a demand for control authority transition to a user during the autonomous driving control when the current driving condition is the limit situation, and starts a minimum risk maneuver to transmit a signal for disabling reactivation of the autonomous driving control when control authority is not transferred to the user; and a storage to store a set of instructions and driving condition data to be used by the processor. In particular, the processor demands for engagement of an electronic parking brake device when the vehicle is stopped after the minimum risk maneuver ends.

VEHICLE CONTROL APPARATUS AND VEHICLE CONTROL METHOD

A vehicle control apparatus 10 is provided with an object detecting means detecting an object in a travel direction of a vehicle 30, a restraining means restraining a drive force of the vehicle when the object detecting means detects an object, and a jerk acquiring means acquiring a jerk in a travel direction on the basis of a behavior of the vehicle. When the accelerator of the vehicle is actuated while the vehicle is in a state in which the drive force of the vehicle is restrained, and the speed of the vehicle is lower than a predetermined value, the restraining means increases the drive force, and decreases a post-increase drive force on the basis of the jerk acquired by the jerk acquiring means.
