Range Rover Evoque: Parking Aid - Overview


The parking aid system provides an audible warning to the driver when any obstacles are in the path of the vehicle during forward or reverse parking maneuvers. The system consists of four ultrasonic sensors in the front bumper and four ultrasonic sensors in the rear bumper, a parking aid module and a parking aid switch.

At low speeds, the parking aid module uses the ultrasonic sensors to monitor the area around the front and rear bumpers.

If an object is detected within a monitored area, the module then outputs a warning using the audio system speakers. The sensors can detect solid objects such as posts, walls and other vehicles and can also detect less solid objects such as a wire mesh fence. Objects very close to the ground may not be detected, but because of their low height may not cause damage to the vehicle.

The parking aid system comprises the following components:

The parking aid module communicates via the medium speed CAN (controller area network) bus with the audio system via the Integrated Control Panel and the Touch Screen Display. The audio system then outputs the applicable warning tones from the front or rear speakers when an object is detected. The high speed CAN bus is used to collect vehicle data from other vehicle systems.

Park Assist - Overview

NOTE: Park assist is not available to all markets.

The optional park assist system operates using two sensors mounted in the front wheel arch moldings, together with parking aid sensors, front and rear.

To parallel park the driver switches on the park assist function prior to identifying a potential parking space and slowly drives past the space. The sensors in the front arch moldings scan the size of the parking space as the vehicle is driven past it. The park assist control system informs the driver if the parking space is big enough to park the vehicle.

The driver is alerted to a suitable parking space on the passenger side via a graphical representation in the instrument cluster message center. If the driver decides to park on the driver's side of the vehicle the direction indicator must be operated. This action will prioritize driver's side parking space information which will be presented to the driver in the message center.

If there is sufficient space, the driver stops the vehicle, selects reverse gear and lets go of the steering wheel.

The park assist system alerts the driver to the intended reverse path, displaying information in the instrument cluster message center. Park assist then actively supports the driver by taking over the steering control and parks the vehicle in the available space.

Where a kerb is present its position is also taken into account for the calculation of the parking trajectory. If there is a lowered kerb (or none at all), the system calculates a trajectory to align the vehicle with the vehicle parked in front.

The driver continues to brake, accelerate, apply the clutch and select the correct gear. Park assist will instantly de-activate if the vehicle speed is too high or if the driver takes over the steering maneuver.

The park assist function can be switched on or off at any time by the driver using a switch located next to the 'park aid' switch. The switch is illuminated by a red LED (light emitting diode) when the system is on.

When the park assist function is switched on and prior to each separate stage of the parking maneuver the system carries out a self-check procedure.

During the park assist maneuver both front and rear parking aid sensors are active.

To activate the park assist 'search for a space' function the vehicle must be in a forward gear and travelling below 18 mph (30 km/h). Above this speed the system de-activates, only re-activating when the speed drops back below the set speed threshold. The search system is not active in reverse gear.

During the park assist reverse and forward maneuvers the system is only active up to a vehicle speed of 10 mph (16 km/h) with a warning of increased speed at 4 mph (7 km/h). The system de-activates above 10 mph (16 km/h).

The system will cancel if any force is placed upon steering wheel during any part of the parking maneuver.

Camera System - Overview

The proximity camera system provides the driver with a visual-aid when maneuvering the vehicle at low speeds. The system uses a dedicated control module to capture the camera data and display the resulting images on the TSD (Touch Screen Display), providing the driver with a 360
