| 发明名称 | Method for determining wastegate valve lift | ||
| 摘要 | Systems and methods for determining the lift of a wastegate valve are provided. Methods comprise determining a relation between an actuator position and a lift of a wastegate valve at engine start-up in a temperature range. The relation may be modified based on a difference between a desired boost level and an actual boost level. | ||

| 主权项 | 1. A method of controlling boost of a turbocharged internal combustion engine having a wastegate valve, comprising: via a controller including a non-transitory computer-readable medium, and based on sensors sensing an engine temperature, an actuator position, and boost identifying a relation between an actuator position and a lift of a wastegate valve at engine start-up in an engine temperature range; and after start-up, modifying the relation between the actuator position and the lift of a wastegate valve based on a difference between a desired boost level and an actual sensed boost level via adjusting at least one of the actuator position and the lift of a wastegate valve. | ||
