BRAKING FORCE CONTROLLER AND VEHICLE

A braking force controller causes a first actuator unit to generate a target jerk when the target jerk is equal to or larger than a first jerk, causes the first actuator unit to generate the first jerk and a second actuator unit to generate a jerk obtained by subtracting the first jerk from the target jerk as an additional jerk when the target jerk is smaller than the first jerk and equal to or larger than the sum of the first jerk and a second jerk, and causes the first actuator unit to generate the first jerk and the second actuator unit to generate the second jerk as the additional jerk when the target jerk is smaller than the sum of the first jerk and the second jerk.

Unintended vehicle motion alert system

A driver alert arrangement for a motor vehicle includes a sensor detecting that the motor vehicle is in motion and transmitting a signal indicative of whether the motor vehicle is in motion. A driver monitoring camera captures images of a human driver of the motor vehicle. An electronic processor is communicatively coupled to the sensor, the driver monitoring camera, and to a user interface. The electronic processor receives the signal from the sensor, receives the images captured by the driver monitoring camera, determines from the images where the driver is looking, and alerts the driver via the user interface that the motor vehicle is in motion. The alerting is dependent upon the signal and where the driver is looking.
