The invention relates to a restarting method for automatically starting an internal combustion engine (2) of a motor vehicle (3) by means of a brake pedal actuation, comprising the following steps: detecting a brake pressure (p) by means of a brake pressure sensor (14); emitting a corresponding brake pressure signal sequence to a control device (13); determining a brake pressure profile (p.sub.pr) from the brake pressure signal sequence; determining a reference pressure value (p.sub.R) from the brake pressure profile; detecting a brake release status, wherein, with the release of a brake pedal, a brake pressure decrease (Δp) is detected based on the determined reference pressure value (p.sub.R), with said decrease exceeding a pressure decrease limit value (Δp.sub.G); emitting a starting signal (S.sub.WS) to a starter (15) for starting the internal combustion engine (2), if the brake release status has been detected. The invention also relates to a restarting assembly for a motor vehicle (1) for carrying out a method of this type.

Autonomous vehicle takeover based on restricted areas includes receiving position data of a vehicle, the position data indicating a position of a vehicle traveling in an area, correlating the received position data to a map including mapped areas designated as non-roadway areas, where the correlating determines that the vehicle is traveling in a designated non-roadway area, checking one or more restrictions placed on vehicular travel in the non-roadway area in which the vehicle is traveling and, based on the one or more restrictions, performing processing to undertake action(s), the action(s) including controlling function(s) of the vehicle.

A method for enabling a driving assistance function after an accident of a vehicle. The method initially including a reading-in step, in which at least one crash signal, as well as sensor data of at least one vehicle sensor and/or actuator data of at least one vehicle actuator, are read in. The reading-in step is executed while the vehicle is driven with the driving assistance function switched off. The method further includes processing the read-in sensor data and/or actuator data to determine a deviation from expected sensor data and/or expected actuator data; the processing then being carried out, if the crash signal signals an accident that has occurred. The method includes enabling the driving assistance function and/or the vehicle actuator, if the sensor data and/or the actuator data fulfill an enabling criterion within a predetermined time window and/or within a predetermined travel route of the vehicle.
