A vehicle security unit is for a vehicle including at least one data communications bus, an On-Board Diagnostic (OBD) port coupled to the at least one data communications bus, and a vehicle tracking unit to be coupled to the OBD port. The vehicle security unit may include a security unit housing, a short-range security wireless device carried by the security unit housing, and a vehicle security controller carried by the security unit housing and configured to establish a wireless communication link via the short-range security wireless device with the vehicle tracking unit and communicate via the at least one data communications bus responsive to the communication link.

A method and to a control device for controlling a haptic accelerator pedal in a motor vehicle includes displacing a pedal lever in an actuation direction between a rest position and a maximally actuated position. The pedal lever is configured to be excited by an actuator by exerting a counter force against the actuation direction to generate a haptically perceivable signal. A current position of the pedal lever relative to a current position of the actuator is determined outside the phases for generating the haptically perceivable signal, and the actuator is subsequently controlled in such a manner that the actuator actively follows a change in the determined position of the pedal lever. The positional control is configured to prevent interfering influences on the pedal lever by the actuator.

The disclosure relates to a method for operating a portable input device to control a motor vehicle. The input device has a pressure-sensitive touchscreen. The input device generates control signals to control the motor vehicle, and transmit said signals to the motor vehicle. The control signal has at least one determinable parameter. The input device is designed to capture a pressure value of an actuating force of the touchscreen, and determine the parameter according to the captured pressure value.

Managing sound levels at an IHS, including determining, for each time duration over a first time period, multiple instantaneous sound levels of the time duration of an environment of the IHS; calculating, for each time duration over first time period, an average sound level of the time duration based on the multiple instantaneous sound levels of the time duration; determining, based on the average sound level of each time duration over the first time period, a lowest average first sound level for first time period; setting the lowest average first sound level as an ambient sound level of the environment of the IHS for the first time period; adjusting, for the first time period, a fan speed of a fan based on the ambient sound level of environment such that a noise level of the fan is less than the ambient sound level of environment for the first time period.
