Systems and methods for determining the location of a vehicle are disclosed. In one embodiment, a method for localizing a vehicle includes driving over a first road segment, identifying by a first localization system a set of candidate road segments, obtaining vertical motion data while driving over the first road segment, comparing the obtained vertical motion data to reference vertical motion data associated with at least one candidate road segment, and identifying, based on the comparison, a location of the vehicle. The use of such localization methods and systems in coordination with various advanced vehicle systems such as, for example, active suspension systems or autonomous driving features, is contemplated.

A trailer for use with a towing vehicle having a first connector. The trailer includes a connector assembly, a plurality of wheels, and a trailer assist assembly. The connector assembly includes a second connector and at least one sensor. The second connector is configured to be coupled to the first connector to thereby couple the trailer to the towing vehicle. The at least one sensor is configured to detect forces applied to at least a portion of the connector assembly. The trailer assist assembly includes a control system and at least one electric motor. The control system is configured to control operation of the at least one electric motor, receive sensor signals from the at least one sensor, and use the sensor signals to determine when to operate the at least one electric motor. The at least one electric motor is operable to drive the plurality of wheels.

A representation of a first set of weights associated with a vehicle prior to a drive are received, the vehicle including a plurality of axles, a plurality of wheels attached to the plurality of axles, and a load. A warning is caused to be output in response to at least one weight from the first set of weights being outside a predetermined range. Longitudinal and lateral dynamics associated with the vehicle during the drive are determined. A second set of weights associated with at least one axle from the plurality of axles during the drive are determined. A determination is made if at least one remedial action should be performed based on the longitudinal dynamics, the lateral dynamics, and the second set of weights. In response to determining that the at least one remedial action should be performed, the at least one remedial action is caused to be performed.

A power assist device may include a motor, a motor driving circuit, sensors to output signals in accordance with a rotational speed of the wheel, a memory, and a signal processor. The memory stores information of a parameter defining a transfer function that interrelates a total torque to be input to the vehicle and a rotational speed of the wheel, and an inverse transfer function thereof. Based on the inverse transfer function, the signal processor determines an estimated value of total torque from a detected value of rotational speed of the wheel. Moreover, based on the transfer function, the signal processor updates at least a portion of the information of the parameter so that, for example, an error between a detected value of rotational speed of the wheel and an estimated value of rotational speed of the wheel as determined from the estimated value of total torque is reduced.

A method for estimating the speed of a motor vehicle includes defining a first speed threshold that corresponds to a minimum speed value supplied by a vehicle wheel angular speed sensor, defining a second speed threshold that is greater than the first, estimating low speed values when the vehicle is running below the first speed threshold by using an estimation method of adaptive filtered type, measuring high speed values when the vehicle is running above the second speed threshold by using vehicle speed values supplied by the wheel angular speed sensor, and in the intermediate zone between the first and second speed thresholds, mixing high speed with low speed.

A longitudinal vehicle speed sensor for a vehicle includes a first sensor configured to generate a first measured speed based on one of a wheel speed of the vehicle receiving output torque from a drive unit and an output of a global positioning system (GPS). A second sensor is configured to generate a second measured speed. A speed weighting module is configured to apply a first weight to the first measured speed to generate a first weighted speed. A speed weighting module is configured to apply a second weight to the second measured speed to generate a second weighted speed. An output module is configured to generate a speed estimate based on the first weighted speed and the second weighted speed.

Disclosed herein are an autonomous vehicle and a method of controlling the same. The autonomous vehicle controller may determine a lane on which a first vehicle is currently travelling, determine a second vehicle that is ahead of the first vehicle, determine, based on receiving from a steering wheel an indication of changing a travelling direction of the first vehicle and while the first vehicle is in an autonomous driving mode, whether the first vehicle is travelling along a predetermined route at an entry point of a ramp, and control, based on determining whether the first vehicle is travelling along the predetermined route at the entry point of the ramp, a route and a speed of the first vehicle.
