Patent Images
1. A controller assembly for use in controlling a utility vehicle having a drive function and an auxiliary function, the controller assembly comprising:
- a housing defining an interior space for containing a plurality of transistors;
an input connector extending from a first portion of the housing, the input connector configured to relay input from the one or more input sensors to one or more of the plurality of transistors; and
a terminal block assembly extending from a second portion of the housing, the terminal block assembly comprising;
a first set of posts for powering a first electric drive motor associated with the drive function of the utility vehicle;
a second set of posts for powering a first electric auxiliary motor associated with the auxiliary function of the utility vehicle; and
a third set of posts for connecting the controller assembly to a power source;
wherein each post extends through an opening in the housing.
