Abstract
Methods and systems are provided for a vehicle adapted to be operated based on fuel combustion or electric power. In one example, an accessory train of the vehicle, including an air conditioning pump and a power steering pump, may be operated according to a first mode or according to a second mode based on a power system of the vehicle. When in the second mode, the vehicle may be instructed to coordinate operation of the air conditioning pump and the power steering pump.
Claims19
A vehicle comprising:
- a frame;
- an accessory train installed within the frame, the accessory train including a belt driving a power steering pump and an air conditioning (AC) compressor;
- and
- a controller storing a first set of instructions and a second set of instructions in a memory of the controller, the first set of instructions executable to operate the accessory train when the controller detects an engine is installed in the frame, the second set of instructions executable to operate the accessory train when the controller detects a traction motor and not an engine is installed in the frame.
A line of vehicles comprising:
- a first vehicle including:
- an internal combustion engine;
- a first accessory train driven by the internal combustion engine, the first accessory train including a first belt driving a first power steering pump and a first AC compressor;
- and
- a first controller adapted to refer to a first set of instructions, the first set of instructions providing instructions for the first vehicle;
- and
- a second vehicle including:
- a traction motor;
- a second accessory train, the second accessory train driven by an electric motor and including a second belt driving a second power steering pump and a second AC compressor;
- and
- a second controller adapted to refer to a second set of instructions, the second set of instructions providing instructions for the second vehicle;
- wherein, in the first vehicle, the first power steering pump and the first AC compressor are operated simultaneously and, in the second vehicle, the second power steering pump and the second AC compressor are operated in a coordinated manner.
A system for operating components of an accessory train of a vehicle, the components including a belt, a belt-driven power steering pump, and a belt-driven air conditioning (AC) compressor, comprising:
- a controller including memory with instructions stored therein executable to:
- in a first mode, in response to detection of a presence of an internal combustion engine, operate components of the accessory train as demanded by an operator, including operating the AC compressor independently of the power steering pump;
- and
- in a second mode, in response to detection of an absence of the internal combustion engine, operate the AC compressor in coordination with the power steering pump.
