Closure latch assembly and electronic control systems for the closure latch assembly

A closure latch assembly, comprising:

• a ratchet and a single pawl, the ratchet being moveable between a striker capture position and a striker release position, the pawl being moveable between a ratchet holding position, whereat the ratchet is maintained in the striker capture position, and a ratchet release position, whereat the ratchet is biased toward the striker release position;
• and
• a power actuator operably coupled to a power release chain, the power release chain having at least three torque multiplication stages and an output operably coupled to the pawl for pulling the pawl to move from the ratchet holding position toward the ratchet release position,
• wherein the output is operably coupled to the pawl via a link arm having a slot extending between a first drive end and a second drive end, and the output having an actuation feature disposed in the slot for sliding lost motion movement between the first drive end and the second drive end to pull the pawl form the ratchet holding position toward the ratchet release position.

• and
• a power actuator operably coupled to a multistage power release chain having at least three stages, including a final stage, of torque multiplication, wherein each stage has an input and an output, wherein an application of force at the input causes a corresponding force at the output, the output from one stage drives the next stage in the release chain to impart a pulling force on the pawl to pull the pawl to the ratchet release position, wherein the output of the final stage is configured to move a drive pin,
• wherein a link arm operably couples the drive pin to the pawl, wherein the link arm has a slot extending between a first drive end and a second drive end, and the drive pin is disposed in the slot for sliding lost motion movement between the first drive end and the second drive end to pull the pawl form the ratchet holding position toward the ratchet release position.
