Abstract
Electronic control systems and related control methods for controlling electric drive motors for propelling a vehicle and electric auxiliary motors for performing work, such as electric deck motors for mower blades. The apparatus is shown in use with a vehicle that includes a mowing deck. Features of the control systems allow for safe and efficient use of the vehicle. Controller assemblies and packaging for electronic control systems of electric motors utilized in utility vehicles or other power equipment are also disclosed. The controller assemblies are packaged for robust design and heat dissipation, while collectively housing the controllers, switches and sensors needed to operate multiple motors performing different functions, or the same function in serial.
