Abstract: Methods and systems are provided for controlling vehicle moding in response to a variety of driving conditions. The system comprises an input device configured to receive first and second inputs, a vehicle subsystem, and a controller coupled to each of the vehicle subsystem and the input device. The vehicle subsystem is configured to produce a parameter related to the driving condition in the first mode. The controller is configured to determine the driving condition from the parameter, control the vehicle subsystem to operate in a first mode based on the first input, and control the vehicle subsystem to operate in a second mode in response to one of the driving condition and the second input.

Abstract: A control circuit for an active engine mount is provided, including an electrical bridge circuit, and a pulse-width modulation (‘PWM’) circuit. The PWM circuit receives an input signal from a controller, and generates first and second PWM output signals. The first PWM signal, derived from the input signal, controls first and third switches of the electrical bridge circuit. The second PWM signal comprises a digitally inverted signal of the first PWM signal, and controls second and fourth switches of the electrical bridge circuit. First and second outputs of the bridge circuit are connectable to first and second terminals of the mount device. The controller receives an input signal from crank and cam sensors, as part of the control scheme.
