Mapping a steering device/sensor

In a steering system comprised by a PVED-CLS and an OSPE, EHi-E or EHPS valve, following sensors are mandatory,
therefore these sensors must be present on the CAN bus.
- SASAIID
- Vehicle speed sensor
- MMI interface
In a steering system comprised by a PVED-CLS and an EHi-H valve, following sensors are mandatory, therefore these
sensors must be pressent on the CAN bus.
- Vehicle speed sensor
- MMI interface
An EHi-H system cannot include a SASA sensor, meaning that fast-steer and EFU are not available.
Additionally, for auto-guidance, closed loop joystick steering, EFU & soft stop functions a wheel angle sensor needs to
be configured in the system, see Section 8.1 and section 8.1.1. The wheel angle sensor sub-system can be CAN based or
Analogue based. If it is analogue based, WAS may be connected to the analogue input pins of the PVED-CLS; AD1 and
AD2 for analogue dual channel sensor sub-system and AD1 for single channel sensor sub-system.
In addition to the sensors and steering devices mentioned above, it is possible to map the cut-off valve (for OSPE/EHi-
E/EHi-H systems), GPS (for auto-guidance steering), a road switch and a single AUX steering device (open loop- or closed
loop joystick, or a mini-steering wheel).
Important
Disabling the wheel angle sensor eliminates the possibility of closed loop steering and some of the offered safety functions.
For more details, please see the Danfoss document, PVED-CLS Safety Manual.
6.1.1

Valid Sensor Combinations

Following sensor configurations shall be followed
1. Only one analogue device/sensor may be present in the system i.e. either Analogue joystick or Analogue wheel
angle sensor.
2. If no wheel angle sensor is present in the system then configurations shall be done according to section 8.1.1.
3. If Elobau Joystick is present in the system the configurations shall be done according to section 11.12.4
For mapping a steering device, the parameter controlling the sensor or steering device presence, needs to be enabled.
Below are the parameters required for sensor configuration.
