Abstract
Methods and apparatus to compensate for body roll in vehicle weight calculations are disclosed. An example method includes receiving sensor data from sensors of a vehicle, determining a weight of the vehicle and determining a body roll of the vehicle. The example method further includes comparing the body roll to a threshold and, if the body roll satisfies the threshold, adjusting the determined weight of the vehicle based on the determined body roll and properties of a suspension system of the vehicle.
Claims14
An apparatus, comprising:
- a sensor input to receive sensor data from sensors of a vehicle;
- a weight determiner to determine a weight of the vehicle based on the sensor data;
- a roll calculator to determine a body roll of the vehicle based on the sensor data;
- a threshold determiner to determine a roll threshold based on at least one of a make of the vehicle, a model of the vehicle, or a suspension system of the vehicle;
- a roll threshold comparator to compare the body roll to the roll threshold;
- a force angle characteristic determiner to determine a suspension force angle characteristic;
- a weight adjuster to, when the body roll satisfies the roll threshold, adjust the determined weight of the vehicle based on the determined body roll and the suspension force angle characteristic;
- and
- a vehicle system interface to adjust a driving characteristic of the vehicle based on the adjusted weight.
A method comprising:
- receiving sensor data from sensors of a vehicle;
- determining a weight of the vehicle based on the sensor data;
- determining a body roll of the vehicle based on the sensor data;
- determining a roll threshold based on at least one of a make of the vehicle, a model of the vehicle, or a suspension system of the vehicle;
- comparing the body roll to the roll threshold;
- determining a suspension force angle characteristic;
- when the body roll satisfies the roll threshold, adjusting the determined weight of the vehicle based on the determined body roll and the suspension force angle characteristic;
- and
- adjusting a driving characteristic of the vehicle based on the adjusted weight.
A non-transitory machine-readable storage medium including instructions which, when executed, cause a processor to at least:
- receive sensor data from sensors of a vehicle;
- determine a weight of the vehicle based on the sensor data;
- determine a body roll of the vehicle based on the sensor data;
- determine a roll threshold based on at least one of a make, a model, or a suspension system of the vehicle;
- and
- compare the body roll to the roll threshold;
- determine a suspension force angle characteristic;
- when the body roll satisfies the roll threshold, adjust the determined weight of the vehicle based on the determined body roll and the suspension force angle characteristic;
- and
- adjust a driving characteristic of the vehicle based on the adjusted weight.
