ETS Electronical Truck Steering

Variations in vehicle wheel base or axle position is easy to set by software programming while all hardware components remain unchanged. The ETS is fully redundant and fail safe while the hydraulic cylinder is equipped with a locking-in-centre position.

STEERING PERFORMANCE
The steering performance is vehicle speed related. From 0 – 25 km/h the tag axle is allowed to steer the maximum defined angle. From 25 to 45 km/h the maximum turning angle is reduced step by step by the software and at 45 km/h the steering movement stops and the axle is locked in the mid position.

FAIL SAFE
The system is of the so called Fail-Safe type. When a failure is detected in the system it will enter in a safe mode (non steering) with the axle returned to the mid position and hydraulically locked with help of a constant pressurized centering system.
The steering system is fulfilling the steering regulation R79 Annex 6 and the EMC regulation R10-05. The Power Pack consist of an E-motor 2kW. These axle solutions are pre-assembled and in case of ETS the sensor and hydraulic cylinder are set in the correct zero-position ready for plug and play.

NEW GENERATION ETS

• The next generation ETS is called MK3.
• The development is made in linde with the Automotive Spice.
• MK3 is ISO26262 certified.
• MK3 is  available with a maximum functional safety level ASIL-C.
• Several standardised diagnosing formats are possible, ODX, OTX, UDS.
• The ETS will also be in line with the cyber security regulation UN R155/R156 and ISO21434.
• The ECU controller is suitable for Chassis mounting.
