## Abstract

Please replace the original Abstract with the following new Abstract: A steering system for a vehicle includes a steering gear, two knuckles of two steerable wheels, a steering actuator, a plurality of sensors, and a processing unit. The steering gear is connected to a first knuckle of the two knuckles and the steering gear is connected to a second knuckle of the two knuckles. The steering gear is connected to the steering actuator. The sensors are mounted at locations associated with the steering gear. Each of the plurality of sensors is configured to acquire steering system position information. Each of the plurality of sensors are configured to provide acquired steering system information to the processing unit.

## Claims

### Claim at position 1

1-10. (canceled)

### Claim 11

A steering system for a vehicle, the steering system comprising:
a steering gear;
two knuckles of two steerable wheels;
a steering actuator;
a plurality of sensors; and
a processing unit;
wherein, the steering gear is connected to a first knuckle of the two knuckles and the steering gear is connected to a second knuckle of the two knuckles;
wherein, the steering gear is connected to the steering actuator;
wherein, the plurality of sensors are mounted at locations associated with the steering gear;
wherein, each of the plurality of sensors is configured to acquire steering system position information; and
wherein, each of the plurality of sensors are configured to provide the acquired steering system information to the processing unit.

### Claim 12 (depends on 11)

The steering system according to claim 11, wherein
at least one of the plurality of sensors is configured to measure a steering position on at least one of the two knuckles and/or an associated connection rod.

### Claim 13 (depends on 11)

The steering system according to claim 11, wherein
at least one first sensor of the plurality of sensors is configured to measure a steering position on the first knuckle and/or associated connection rod, and
at least one second sensor of the plurality of sensors is configured to measure a steering position on the second knuckle and/or associated connection rod.

### Claim 14 (depends on 11)

The steering system according to claim 11, wherein
the connection between the steering gear and two knuckles comprises an output shaft of the steering gear, and
at least one of the plurality of sensors is configured to measure a steering position on the output shaft.

### Claim 15 (depends on 11)

The steering system according to claim 11, wherein
the connection between the steering gear and steering actuator comprises a torque transmitting unit or input shaft, and
