Fuel Scheduling

Rate-limited fuel valve command with emergency cutoff.

Header: core/ecu_fuel.h

void ecu_fuel_init(ecu_fuel_state_t *state)

Initialise fuel state.

Parameters:

• state – [out] Fuel state to initialise.

ecu_fuel_output_t ecu_fuel_compute(float target_pct, float dt, const ecu_config_t *cfg, ecu_fuel_state_t *state)

Compute fuel output with rate limiting.

Parameters:

• target_pct – [in] Desired fuel percentage (0–100).

• dt – [in] Time step in seconds.

• cfg – [in] Engine configuration (ramp rate, limits).

• state – [inout] Fuel state (updated in place).

Returns:

Fuel output with commanded and actual percentages.

void ecu_fuel_cutoff(ecu_fuel_state_t *state)

Activate emergency fuel cutoff.

Parameters:

• state – [inout] Fuel state.

void ecu_fuel_release(ecu_fuel_state_t *state)

Release emergency fuel cutoff.

Parameters:

• state – [inout] Fuel state.
