Embodiment Construction

[0012] Reference will now be made in detail to the exemplary embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts. Although exemplary embodiments of the present invention are described with reference to haul trucks having diesel engines for use in the surface mining industry, embodiments of the present invention are also generally suitable for use with internal combustion engines and vehicles employing such engines. For example, a vehicle may be an off-highway vehicle ("OHV") designed to perform operations associated with a particular industry (such as mining, construction, agriculture, etc.), and may include haul trucks, cranes, bulldozers, mining machines, agricultural Equipment, tractors, material handling equipment, earthmoving equipment, etc. Alternatively or additionally, the vehicle may be a road vehicle, such as...

Abstract

A control system for a vehicle includes an electric drive system associated with a first set of wheels. The electric drive system is configured to selectively provide electric motive power to the first set of wheels to propel the vehicle and electric retarding to slow the vehicle. The system further includes a friction brake system associated with one of the first set of wheels or a second set of wheels, a drive system control unit, and a friction brake control unit in electrical communication with the drive system control unit. The drive system control unit is configured to communicate with the friction brake control unit to control an amount of friction brake application during vehicle stops and starts on grade.

Description

technical field [0001] Embodiments of the invention generally relate to vehicle control. Other embodiments relate to control systems and methods for braking a vehicle. Background technique [0002] Large off-highway vehicles ("OHVs"), such as mining vehicles used to haul heavier payloads mined from surface mines, are well known and typically use powered wheels for propelling or decelerating the vehicle in an energy efficient manner. Efficiency is typically achieved by using a high horsepower diesel engine along with an alternator, main traction inverter and a pair of wheel drive assemblies housed within the vehicle's rear tires. The diesel engine is directly coupled to the alternator such that the diesel engine drives the alternator. The alternator powers the main traction inverter, which supplies electrical energy at a controlled voltage and frequency to the electric drive motors of the two-wheel drive assemblies. Each wheel drive assembly houses a planetary gear transmi...
