Automatic parking control method and automatic parking control apparatus for vehicles
An automatic parking control device includes an automatic parking controller that carries out automatic parking control, and a park-by-wire controller in which a park lock is automatically engaged when automatic parking is completed at a target stopping position by the automatic parking control. The park-by-wire controller determines whether a system abnormality would occur, in which the park-by-wire system does not operate normally during the automatic parking control. The automatic parking controller prohibits the starting of the automatic parking control upon determining that the system abnormality would occur before the automatic parking control is started.
METHOD FOR MONITORING AN ABS CONTROL PROCEDURE IN AN ELECTRICALLY CONTROLLABLE BRAKE SYSTEM AND ELECTRONICALLY CONTROLLABLE BRAKE SYSTEM
A method for monitoring an ABS control procedure in an electrically controllable brake system in a vehicle includes reading in input signals, wherein based on the input signals it is possible to derive currently prevailing control variables for the ABS control procedure and ABS control parameters that relate to a brake slip-controlled actuation of an ABS control valve of the brake system. The method further includes checking whether it follows that an activation of any ABS control valve that is allocated to a wheel of the vehicle is requested, and whether it follows that an ABS brake slip incident is present at at least a first wheel of the vehicle, and/or whether, based on the ABS control parameters, it follows that further ABS control valves, which are allocated at least to one second wheel of the vehicle, implement correctly a brake slip-controlled activation.

METHOD FOR CONTROLLING A BRAKING SYSTEM OF A VEHICLE AND RELATED SYSTEM
A method for controlling a braking system of a vehicle may include detecting, by a first plurality of detection devices distributed on the braking system of the vehicle, first information representative of a condition of motion of the vehicle. The method may also include detecting, by a second plurality of detection devices belonging to a first driver assistance sub-system associated with the vehicle, second information representative of a condition of motion of the vehicle. The method may also include determining, by a first data processing block, a first control signal of a braking module of the vehicle based on the first information and the second information. The method may also include controlling, by the first data processing block, the braking module of the vehicle based on the determined first control signal.
Vehicle brake pad monitoring
A method for operating a vehicle is disclosed. The method includes receiving, at a processor, a brake pad signal from a braking system of the vehicle, each brake pad signal including information on a pad wear value associated with a set of source brake pads. The processor determines whether the pad wear value from the brake pad signal exceeds a pad wear threshold and in response to the brake pad signal exceeding the pad wear threshold further determines a degradation delay from an initial detection of the pad wear threshold being exceeded wherein the degradation delay is determined based on vehicle operating data. The processor causes the disabling of one or more first level vehicle features including an autonomous or semi-autonomous mode of operating the vehicle based on the degradation delay reaching a delay threshold.

In-Vehicle Electronic Control System
Fail-safe is performed appropriately when an automatic driving ECU has a failure. Provided is an in-vehicle electronic control system including a recognition device that recognizes a situation outside a vehicle, a track calculation unit that calculates a track on which the vehicle travels, a failure diagnosis unit that diagnoses a failure of the track calculation unit, and an output unit that outputs a control signal used to control the vehicle, in which a control signal generated based on a brake control instruction generated by the recognition device and a control signal generated based on a track control instruction generated by the track calculation unit are input to the output unit, and when the failure diagnosis unit diagnoses that the track calculation unit has a failure, the output unit outputs a control signal generated based on the brake control instruction generated by the recognition device.
METHOD FOR CONTROLLING A BRAKE SYSTEM OF A VEHICLE
A method for controlling a brake system of a vehicle comprises detecting a failure of a sensor for at least one of the vehicle wheels, checking whether a brake control function is being executed at the time of the failure, continuing the brake control function if a brake control function is being executed and deactivating the brake control function when execution of the brake control function has been completed. If no brake control function is being executed at the time of the failure then executing the brake control function if a brake control function is initiated within a defined period of time after the failure, and deactivating the brake control function after execution of the brake control function has been completed and the period of time has expired or if no brake control function has been initiated within the defined period of time.

APPARATUS AND METHOD FOR DETERMINING WHEEL CONDITION
An apparatus for determining a wheel condition on whether wheel locking occurs in each wheel of a vehicle having a main brake apparatus and an auxiliary brake apparatus. The apparatus includes: a WSS (Wheel Speed Sensor) configured to primarily detect whether wheel locking occurs; a TPMS (Tire Pressure Monitoring System) configured to secondarily detect whether wheel locking occurs; and a control unit configured to determine, when the WSS fails, a wheel condition indicative of whether wheel locking occurs in each wheel, by using information detected through the TPMS.
