Chapter 38 Security, Navigation, and Advanced Driver Assistance Systems 515 Copyright Goodheart-Willcox Co., Inc. ASE-Type Questions 1. Keypad-type keyless entry systems are being discussed. Technician A says these systems use a key fob that contains a small transmitter to lock and unlock the vehicle’s doors. Technician B says the five numbers on the keypad must be pressed in the correct sequence for the doors to unlock. Who is right? (A) A only (B) B only (C) Both A and B (D) Neither A nor B 2. Technician A says navigation systems use a satellite global positioning system to display the geographic location of the vehicle. Technician B says the vehicle’s on-board computer compares satellite data with a large database of roads and highways. Who is right? (A) A only (B) B only (C) Both A and B (D) Neither A nor B 3. What type of device(s) do advanced driver assistance systems (ADAS) use to aid in preventing collisions and improving driver performance? (A) Sensors (B) Cameras (C) ECM (D) All of the above. 4. Technician A says that radar, infrared, and ultrasonic proximity sensors are used to detect nearby objects, such as other vehicles or pedestrians on the road. Technician B says that radar sensors have a weak sensing distance. Who is right? (A) A only (B) B only (C) Both A and B (D) Neither A nor B 5. Technician A says a vehicle’s backup camera gives drivers an obstructed view of objects located behind the vehicle. Technician B says a voice- activated system can be programmed to react to certain words. Who is right? (A) A only (B) B only (C) Both A and B (D) Neither A nor B 6. Technician A says most blind spot warning systems use radar to measure the distance of objects on either side of the vehicle. Technician B says a driver alert system uses cameras on both sides of the driver to detect driver distraction. Who is right? (A) A only (B) B only (C) Both A and B (D) Neither A nor B 7. Technician A says that most lane-keeping systems use four video cameras to follow the middle of the road. Technician B says that radar sensors are used to detect the center of the road. Who is right? (A) A only (B) B only (C) Both A and B (D) Neither A nor B 8. What type of sensor or device does a night vision system use to help the driver see through vision- impairing atmospheric conditions? (A) Radar sensor (B) Infrared sensor (C) Ultrasonic sensor (D) Boolean sensor 9. Technician A says that automatic parking systems are not reliable for parallel parking. Technician B says that they work efficiently and safely. Who is right? (A) A only (B) B only (C) Both A and B (D) Neither A nor B 10. Technician A says many automatic parking systems use sonic proximity sensors. Technician B says that no one makes a car with an automatic parking feature. Who is right? (A) A only (B) B only (C) Both A and B (D) Neither A nor B
