Steering 4 L2

How many types of Electrical Assisted Steering are there?

• Two

• Three

• One

• Four

Which of these is not a component of EPAS?

• Complex wiring loom

• Steering potentiometers

• Planetry gearset

• Steering speed sensor

The motor used in a EPAS is BLDC type motor?

• True

• False

What inputs are required for the ECU to operate steering?

• Direction, Speed of turn, Effort of turn

• Engine speed, Effort of turn, Speed of turn

• Vehicle speed, Engine speed, Effort of turn

• Vehicle speed, Direction, Effort of turn

The ECU recieves information from sensors and relates this to:

• Pre-programmed characteristics

• Full assistance at high speed

• Low assistance at low speed

• Self-driving mode

What is main purpose of planetry gearset?

• Failsafe in case motor fails

• Allow differents amount of effort of motor

• To vary the input speed of motor

• To allow variable geared steering

How does steering movement sensor operate?

• Rotational angle of torsion bar

• Speed steering wheel turns

• Hydraulic pressure exceeds relief valve

• Torsion sensor on the output shaft

What happens if vehicle is held in full lock?

• ECU reduces power to motor

• Hydraulic relief valve opens

• Torque sensor turns off

• Warning lamp illuminates

What is the benefit of EPAS?

• All of the answers

• Reduced fuel consumption

• Additional safety features

• Weight saving

What is lane assist?

• Car remains in chosen lane

• Car automatically changes lane on indication

• Car automatically return to lane after overtaking

• Car can self park
