Disclosed is a system and method for determining a driver's inebriation in a vehicle. The system includes a breathalyzer configured to be provided in an interior space of the vehicle to determine whether the driver is inebriated, through a driver's exhalation; and a controller configured to output a movement request signal for a driver's seat when determination of driver's inebriation by the breathalyzer is required and to control the breathalyzer to start the determination of driver's inebriation when the movement of the driver's seat is completed.

A computer includes a processor and a memory storing instructions executable by the processor to receive an input by a first user setting a maximum speed for a vehicle; prevent a second user from operating the vehicle above the maximum speed; permit the second user to operate the vehicle above the maximum speed upon at least one condition being met; in response to permitting the second user to operate the vehicle above the maximum speed, transmit a first collection of vehicle data to the first user; and in response to the second user failing to stop the vehicle at a stop indicator, transmit a second collection of the vehicle data to the first user.

A profile is automatically generated for an occupant of a vehicle. In one approach, data is collected from an interior of a vehicle to determine whether an occupant is present. If an occupant is present, a local profile is automatically generated. The local profile is sent to a remote computing device. The remote computing device links the local profile to a remote profile stored by the remote computing device. Configuration data is generated by the remote computing device based on linking the local and remote profiles. The configuration data is sent to the vehicle and used by the vehicle to control the operation of one or more components of the vehicle.

A vehicle travel control method and a vehicle travel control device carries out a downshift control of an automatic transmission when a vehicle speed increases from a set vehicle speed during a constant speed travel control by at least a first prescribed value. Subsequent downshift control of the automatic transmission is prohibited upon determining the vehicle speed has increased from the set vehicle speed by at least the first prescribed value due to an operation of an operating element by the driver during constant speed travel control. Downshift control of the automatic transmission is executed upon determining insufficient deceleration of the vehicle exists where the driver is not operating the accelerator pedal during prohibition of the downshift control.

A driving support apparatus is provided with: a first controller programmed to perform a first control, which is to make a speed of a vehicle not to exceed a predetermined speed; a second controller programmed to perform a second control, which is a driving support control that is different from the first control; a preventer configured to prevent the second control on the basis of an operation of an accelerator by an occupant of the vehicle; and a prevention reducer configured to control the preventer to hardly prevent the second control if the first control is performed, in comparison with when the first control is not performed.
