(16 cards)
What is centerline steering?
The steering wheel is level when travelling a straight course
What is tire life?
The ability of the vehicle’s suspension and steering system to provide proper road contact and maximize tire life
What is directional stability?
The ability of a vehicle to maintain a straight course on a level surface without input from the steering wheel
What is returnability?
The ability of the front wheels to return to the straight ahead position from a steered position with little to no input from the steering wheel
What is road isolation?
The ability of the suspension and steering system to diminish road forces and provide comfort for the occupants
What is feedback?
The “feel of the road” required to allow the operator to judge road conditions and maintain control of the vehicle
What is cornering?
The ability of a vehicle to maintain control in a curved path
What is predictability?
