Methods, apparatus, systems, and articles of manufacture are disclosed to use front load estimates for body control are disclosed herein. An example vehicle includes a front axle, a suspension system including a suspension element, and a processor to execute instructions to generate, based on a load on the front axle and a velocity of the vehicle, a body control adjustment, determine a modified body control output based on the body control adjustment and an unmodified body control output, and apply the modified body control output to the suspension element of the vehicle.

Methods and apparatus to use front load estimates for body control

Methods, apparatus, systems, and articles of manufacture are disclosed to use front load estimates for body control are disclosed herein. An example apparatus disclosed herein includes memory including stored instructions, and a processor to execute the instructions to filter sensor data to generate a first load value, the first load value associated with a first load on a front axle of a vehicle, generate, based on the first load value and a velocity of the vehicle, a first body control adjustment value, modify a body control output value with the first body control adjustment value, and apply the modified body control output value to a suspension system of the vehicle.

A system for damping control for a vehicle includes a parameter component and a damping adjustment component. The parameter component is configured to determine one or more driving parameters of a vehicle. The one or more driving parameters include a velocity of the vehicle. The damping adjustment component is configured to adjust damping of suspension of the vehicle during driving based on the one or more driving parameters. The damping adjustment component is also configured to adjust damping of suspension at a zero velocity for a threshold time period in response to transitioning from a non-zero velocity to the zero velocity.

Vehicle damping control

An active vehicle suspension system includes an active damping mechanism operatively coupled to a vehicle wheel and configured for controlling a damping force applied to the wheel responsive to a control signal. A controller is operatively coupled to the damping mechanism and configured for generating a control signal to the damping mechanism responsive to velocity of the wheel in a downward vertical direction. At least one of a timer threshold and velocity threshold, used to determine whether a vehicle wheel has encountered a depression in a road surface, may be varied on a basis of a speed of the vehicle. A damping mechanism for a rear wheel of a vehicle may be controlled on a basis of how a damping mechanism for a front wheel is controlled.

Ride performance optimization in an active suspension system

Methods and systems are provided for generating sufficient vacuum to enable a leak detection routine. While a fuel tank pressure is within mechanical limits, fuel vapors are purged from a canister to an engine with an isolation valve open to generate a desired level of vacuum in the fuel tank. Thereafter, the fuel tank is isolated and leak detection is performed concurrent to the purging.

Method and system for fuel vapor control

A method for controlling an automotive canister purge valve in fluid communication with an evaporative canister includes selecting a purge flow rate of increase for the purge valve based on a hydrocarbon concentration in a fluid stream exiting the evaporative canister, and operating the purge valve based on the selected rate.
